Denton Liu ad6dad0996 *.[ch]: manually align parameter lists
In previous patches, extern was mechanically removed from function
declarations without care to formatting, causing parameter lists to be
misaligned. Manually format changed sections such that the parameter
lists should be realigned.

Viewing this patch with 'git diff -w' should produce no output.

Denton Liu 554544276a *.[ch]: remove extern from function declarations using spatch
There has been a push to remove extern from function declarations.
Remove some instances of "extern" for function declarations which are
caught by Coccinelle. Note that Coccinelle has some difficulty with
processing functions with `__attribute__` or varargs so some `extern`
declarations are left behind to be dealt with in a future patch.

This was the Coccinelle patch used:

	@@
	type T;
	identifier f;
	@@
	- extern
	  T f(...);

and it was run with:

	$ git ls-files \*.{c,h} |
		grep -v ^compat/ |
		xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place

Files under `compat/` are intentionally excluded as some are directly
copied from external sources and we should avoid churning them as much
as possible.

Han-Wen Nienhuys bf1a11f0a1 sideband: highlight keywords in remote sideband output
The colorization is controlled with the config setting "color.remote".

Supported keywords are "error", "warning", "hint" and "success". They
are highlighted if they appear at the start of the line, which is
common in error messages, eg.

   ERROR: commit is missing Change-Id

The Git push process itself prints lots of non-actionable messages
(eg. bandwidth statistics, object counters for different phases of the
process). This obscures actionable error messages that servers may
send back. Highlighting keywords in the sideband draws more attention
to those messages.

The background for this change is that Gerrit does server-side
processing to create or update code reviews, and actionable error
messages (eg. missing Change-Id) must be communicated back to the user
during the push. User research has shown that new users have trouble
seeing these messages.

The highlighting is done on the client rather than server side, so
servers don't have to grow capabilities to understand terminal escape
codes and terminal state. It also consistent with the current state
where Git is control of the local display (eg. prefixing messages with
"remote: ").

The highlighting can be configured using color.remote.<KEYWORD>
configuration settings. Since the keys are matched case insensitively,
we match the keywords case insensitively too.

Finally, this solution is backwards compatible: many servers already
prefix their messages with "error", and they will benefit from this
change without requiring a server update. By contrast, a server-side
solution would likely require plumbing the TERM variable through the
git protocol, so it would require changes to both server and client.

Nguyễn Thái Ngọc Duy e17ca92637 completion: drop the hard coded list of config vars
The new help option --config-for-completion is a machine friendlier
version of --config where all the placeholders and wildcards are
dropped, leaving only the good, completable prefixes for
git-completion.bash to consume.

Nguyễn Thái Ngọc Duy 3ac68a93fd help: add --config to list all available config
Sometimes it helps to list all available config vars so the user can
search for something they want. The config man page can also be used
but it's harder to search if you want to focus on the variable name,
for example.

This is not the best way to collect the available config since it's
not precise. Ideally we should have a centralized list of config in C
code (pretty much like 'struct option'), but that's a lot more work.
This will do for now.

Nguyễn Thái Ngọc Duy 1b81d8cb19 help: use command-list.txt for the source of guides
The help command currently hard codes the list of guides and their
summary in C. Let's move this list to command-list.txt. This lets us
extract summary lines from Documentation/git*.txt. This also
potentially lets us list guides in git.txt, but I'll leave that for
now.

Nguyễn Thái Ngọc Duy 63eae83f8f help: add "-a --verbose" to list all commands with synopsis
This lists all recognized commands [1] by category. The group order
follows closely git.txt.

[1] We may actually show commands that are not built (e.g. if you set
NO_PERL you don't have git-instaweb but it's still listed here). I
ignore the problem because on Linux a git package could be split
anyway. The "git-core" package may not contain git-instaweb even if
it's built because it may end up in a separate package. We can't know
anyway.

This allows us to select any group of commands by a category defined
in command-list.txt. This is an internal/hidden option so we don't
have to be picky about the category name or worried about exposing too
much.

command groups.

Nguyễn Thái Ngọc Duy 6bb2dc0b94 completion: implement and use --list-cmds=main,others
This is part of the effort to break down and provide commands by
category in machine-readable form. This could be helpful later on when
completion script switches to use --list-cmds for selecting
completable commands. It would be much easier for the user to choose
to complete _all_ commands instead of the default selection by passing
different values to --list-cmds in git-completino.bash.

While at there, replace "git help -a" in git-completion.bash with
--list-cmds since it's better suited for this task.

Vikrant Varma e56181060e help: add help_unknown_ref()
When the user gives an unknown string to a command that expects to
get a ref, we could be more helpful than just saying "that's not a
ref" and die.

Add helper function help_unknown_ref() to take care of displaying an
error message along with a list of suggested refs the user might
have meant.  An interaction with "git merge" might go like this:

	$ git merge foo
	merge: foo - not something we can merge

	Did you mean one of these?
	    origin/foo
	    upstream/foo

Nguyễn Thái Ngọc Duy 4470ef9497 help: replace underlining "help -a" headers using hyphens with a blank line
We used to underline a header text, like this:

    This is a header
    ----------------
    content...

But calculating text length so that the dashes align with the text
could get complicated because the text could be in any charset in
translated Git.

There is no point to use this pseudo underline; simply a blank
line would do and it even makes it easier to read:

    This is a header

    content...

While at it, give translators more context to translate, e.g.
e.g.  "git commands available..." instead of "%s available..."

  git wrapper: DWIM mistyped commands

Johannes Schindelin 8af84dadb1 git wrapper: DWIM mistyped commands
This patch introduces a modified Damerau-Levenshtein algorithm into
Git's code base, and uses it with the following penalties to show some
similar commands when an unknown command was encountered:

	swap = 0, insertion = 1, substitution = 2, deletion = 4

A typical output would now look like this:

	$ git sm
	git: 'sm' is not a git-command. See 'git --help'.

	Did you mean one of these?
		am
		rm

The cut-off is at similarity rating 6, which was empirically determined
to give sensible results.

As a convenience, if there is only one candidate, Git continues under
the assumption that the user mistyped it.  Example:

	$ git reabse
	WARNING: You called a Git program named 'reabse', which does
	not exist.
	Continuing under the assumption that you meant 'rebase'
	[...]

First this removes git-help's functions from libgit which are not

again.
