This also fixes the problem of silently ignoring .gitignore if the

This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which
makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce
the same output. Previously only the version without trailing slash
returns the difference (if any).
That's the effect of new ce_path_match(). dir_path_match() is not
executed by the new tests. And it should not introduce regressions.
Previously if path "dir/" is passed in with pathspec "dir/", they
obviously match. With new dir_path_match(), the path becomes
_directory_ "dir" vs pathspec "dir/", which is not executed by the old
code path in m_p_i(). The new code path is executed and produces the
same result.
The other case is pathspec "dir" and path "dir/" is now turned to
"dir" (with DO_MATCH_DIRECTORY). Still the same result before or after
the patch.
So why change? Because of the next patch about clean.c.

"git ls-files -k" needs to crawl only the part of the working tree
that may overlap the paths in the index to find killed files, but
shared code with the logic to find all the untracked files, which
made it unnecessarily inefficient.
* jc/ls-files-killed-optim:
dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage
t3010: update to demonstrate "ls-files -k" optimization pitfalls
ls-files -k: a directory only can be killed if the index has a non-directory
dir.c: use the cache_* macro to access the current index
"ls-files -o" and "ls-files -k" both traverse the working tree down
to find either all untracked paths or those that will be "killed"
(removed from the working tree to make room) when the paths recorded
in the index are checked out. It is necessary to traverse the
working tree fully when enumerating all the "other" paths, but when
we are only interested in "killed" paths, we can take advantage of
the fact that paths that do not overlap with entries in the index
can never be killed.
The treat_one_path() helper function, which is called during the
recursive traversal, is the ideal place to implement an
optimization.
When we are looking at a directory P in the working tree, there are
three cases:
(1) P exists in the index. Everything inside the directory P in
the working tree needs to go when P is checked out from the
index.
(2) P does not exist in the index, but there is P/Q in the index.
We know P will stay a directory when we check out the contents
of the index, but we do not know yet if there is a directory
P/Q in the working tree to be killed, so we need to recurse.
(3) P does not exist in the index, and there is no P/Q in the index
to require P to be a directory, either. Only in this case, we
know that everything inside P will not be killed without
recursing.
Note that this helper is called by treat_leading_path() that decides
if we need to traverse only subdirectories of a single common
leading directory, which is essential for this optimization to be
correct. This caller checks each level of the leading path
component from shallower directory to deeper ones, and that is what
allows us to only check if the path appears in the index. If the
call to treat_one_path() weren't there, given a path P/Q/R, the real
traversal may start from directory P/Q/R, even when the index
records P as a regular file, and we would end up having to check if
any leading subpath in P/Q/R, e.g. P, appears in the index.

:(glob)path differs from plain pathspec that it uses wildmatch with
WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The
difference lies in how '*' (and '**') is processed.
With the introduction of :(glob) and :(literal) and their global
options --[no]glob-pathspecs, the user can:
- make everything literal by default via --noglob-pathspecs
--literal-pathspecs cannot be used for this purpose as it
disables _all_ pathspec magic.
- individually turn on globbing with :(glob)
- make everything globbing by default via --glob-pathspecs
- individually turn off globbing with :(literal)
The implication behind this is, there is no way to gain the default
matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get
new globbing or literal. The old fnmatch behavior is considered
deprecated and discouraged to use.

Currently to fill a struct pathspec, we do:
const char **paths;
paths = get_pathspec(prefix, argv);
...
init_pathspec(&pathspec, paths);
"paths" can only carry bare strings, which loses information from
command line arguments such as pathspec magic or the prefix part's
length for each argument.
parse_pathspec() is introduced to combine the two calls into one. The
plan is gradually replace all get_pathspec() and init_pathspec() with
parse_pathspec(). get_pathspec() now becomes a thin wrapper of
parse_pathspec().
parse_pathspec() allows the caller to reject the pathspec magics that
it does not support. When a new pathspec magic is introduced, we can
enable it per command after making sure that all underlying code has no
problem with the new magic.
"flags" parameter is currently unused. But it would allow callers to
pass certain instructions to parse_pathspec, for example forcing
literal pathspec when no magic is used.
With the introduction of parse_pathspec, there are now two functions
that can initialize struct pathspec: init_pathspec and
parse_pathspec. Any semantic changes in struct pathspec must be
reflected in both functions. init_pathspec() will be phased out in
favor of parse_pathspec().

'git-status --ignored' still scans the work tree twice to collect
untracked and ignored files, respectively.
fill_directory / read_directory already supports collecting untracked and
ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED
flag to enable this has some git-add specific side-effects (e.g. it
doesn't recurse into ignored directories, so listing ignored files with
--untracked=all doesn't work).
The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored
files in dir_struct.entries[] (instead of dir_struct.ignored[] as
DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git.
We don't want to break the existing API, so lets introduce a new flag
DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar
to DIR_COLLECT_FILES, but will recurse into sub-directories based on the
other flags as DIR_SHOW_IGNORED does.
In dir.c::read_directory_recursive, add ignored files to either
dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move
the DIR_COLLECT_IGNORED case here so that filling result lists is in a
common place.
In wt-status.c::wt_status_collect_untracked, use the new flag and read
results from dir_struct.ignored[]. Remove the extra fill_directory call.
builtin/check-ignore.c doesn't call fill_directory, setting the git-add
specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity.
Update API documentation to reflect the changes.
Performance: with this patch, 'git-status --ignored' is typically as fast
as 'git-status'.

The is_excluded and is_path_excluded APIs are very similar, except for a
few noteworthy differences:
is_excluded doesn't handle ignored directories, results for paths within
ignored directories are incorrect. This is probably based on the premise
that recursive directory scans should stop at ignored directories, which
is no longer true (in certain cases, read_directory_recursive currently
calls is_excluded *and* is_path_excluded to get correct ignored state).
is_excluded caches parsed .gitignore files of the last directory in struct
dir_struct. If the directory changes, it finds a common parent directory
and is very careful to drop only as much state as necessary. On the other
hand, is_excluded will also read and parse .gitignore files in already
ignored directories, which are completely irrelevant.
is_path_excluded correctly handles ignored directories by checking if any
component in the path is excluded. As it uses is_excluded internally, this
unfortunately forces is_excluded to drop and re-read all .gitignore files,
as there is no common parent directory for the root dir.
is_path_excluded tracks state in a separate struct path_exclude_check,
which is essentially a wrapper of dir_struct with two more fields. However,
as is_path_excluded also modifies dir_struct, it is not possible to e.g.
use multiple path_exclude_check structures with the same dir_struct in
parallel. The additional structure just unnecessarily complicates the API.
Teach is_excluded / prep_exclude about ignored directories: whenever
entering a new directory, first check if the entire directory is excluded.
Remember the excluded state in dir_struct. Don't traverse into already
ignored directories (i.e. don't read irrelevant .gitignore files).
Directories could also be excluded by exclude patterns specified on the
command line or .git/info/exclude, so we cannot simply skip prep_exclude
entirely if there's no .gitignore file name (dir_struct.exclude_per_dir).
Move this check to just before actually reading the file.
is_path_excluded is now equivalent to is_excluded, so we can simply
redirect to it (the public API is cleaned up in the next patch).
The performance impact of the additional ignored check per directory is
hardly noticeable when reading directories recursively (e.g. 'git status').
However, performance of git commands using the is_path_excluded API (e.g.
'git ls-files --cached --ignored --exclude-standard') is greatly improved
as this no longer re-reads .gitignore files on each call.
Here's some performance data from the linux and WebKit repos (best of 10
runs on a Debian Linux on SSD, core.preloadIndex=true):

For exclude patterns read in from files, the filename is stored in the
exclude list, and the originating line number is stored in the
individual exclude (counting starting at 1).
For exclude patterns provided on the command line, a string describing
the source of the patterns is stored in the exclude list, and the
sequence number assigned to each exclude pattern is negative, with
counting starting at -1. So for example the 2nd pattern provided via
--exclude would be numbered -2. This allows any future consumers of
that data to easily distinguish between exclude patterns from files
vs. from the CLI.

Previously each exclude_list could potentially contain patterns
from multiple sources. For example dir->exclude_list[EXC_FILE]
would typically contain patterns from .git/info/exclude and
core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain
patterns from multiple per-directory .gitignore files during
directory traversal (i.e. when dir->exclude_stack was more than
one item deep).
We split these composite exclude_lists up into three groups of
exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each
exclude_list now contains patterns from a single source. This will
allow us to cleanly track the origin of each pattern simply by adding
a src field to struct exclude_list, rather than to struct exclude,
which would make memory management of the source string tricky in the
EXC_DIRS case where its contents are dynamically generated.
Similarly, by moving the filebuf member from struct exclude_stack to
struct exclude_list, it allows us to track and subsequently free
memory buffers allocated during the parsing of all exclude files,
rather than only tracking buffers allocated for files in the EXC_DIRS
group.

When a pattern contains only a single asterisk as wildcard,

"git ls-files --exclude=t/ -i" does not show paths in directory t/
that have been added to the index, but it should.
The excluded() API was designed for callers who walk the tree from
the top, checking each level of the directory hierarchy as it
descends if it is excluded, and not even bothering to recurse into
an excluded directory. This would allow us optimize for a common
case by not having to check if the exclude pattern "foo/" matches
when looking at "foo/bar", because the caller should have noticed
that "foo" is excluded and did not even bother to read "foo/bar"
out of opendir()/readdir() to call it.
The code for "ls-files -i" however walks the index linearly, feeding
paths without checking if the leading directory is already excluded.

properly call excluded() check for higher hierarchies as necessary.
