Wnen refusing to push a head, we said cryptic "remote 'branch'
object X does not exist on local" or "remote ref 'branch' is not
a strict subset of local ref 'branch'". That was gittish.
Since the most likely reason this happens is because the pushed
head was not up-to-date, clarify the error message to say that
straight, and suggest pulling first.
First noticed by Johannes and seconded by Andreas.

It used to make sense to have git-send-pack talk about the things it sent
when (a) it was a new program and (b) nobody had a lot of tags and
branches.
These days, it's just distracting to see tons of
'refs/tags/xyz': up-to-date
...
when updating a remote repo.
So shut it up by default, and add a "--verbose" flag for those who really
want to see it.
Also, since this makes he case of everything being up-to-date just totally
silent, make it say "Everything up-to-date" if no refs needed updating.

The previous round caught the most trivial case well, but broke
down once index file is updated again. Smudge problematic

This fixes the longstanding "Racy GIT" problem, which was pretty
much there from the beginning of time, but was first
demonstrated by Pasky in this message on October 24, 2005:
http://marc.theaimsgroup.com/?l=git&m=113014629716878
If you run the following sequence of commands:
echo frotz >infocom
git update-index --add infocom
echo xyzzy >infocom
so that the second update to file "infocom" does not change
st_mtime, what is recorded as the stat information for the cache
entry "infocom" exactly matches what is on the filesystem
(owner, group, inum, mtime, ctime, mode, length). After this
sequence, we incorrectly think "infocom" file still has string
"frotz" in it, and get really confused. E.g. git-diff-files
would say there is no change, git-update-index --refresh would
not even look at the filesystem to correct the situation.
Some ways of working around this issue were already suggested by
Linus in the same thread on the same day, including waiting
until the next second before returning from update-index if a
cache entry written out has the current timestamp, but that
means we can make at most one commit per second, and given that
the e-mail patch workflow used by Linus needs to process at
least 5 commits per second, it is not an acceptable solution.
Linus notes that git-apply is primarily used to update the index
while processing e-mailed patches, which is true, and
git-apply's up-to-date check is fooled by the same problem but
luckily in the other direction, so it is not really a big issue,
but still it is disturbing.
The function ce_match_stat() is called to bypass the comparison
against filesystem data when the stat data recorded in the cache
entry matches what stat() returns from the filesystem. This
patch tackles the problem by changing it to actually go to the
filesystem data for cache entries that have the same mtime as
the index file itself. This works as long as the index file and
working tree files are on the filesystems that share the same
monotonic clock. Files on network mounted filesystems sometimes
get skewed timestamps compared to "date" output, but as long as
working tree files' timestamps are skewed the same way as the
index file's, this approach still works. The only problematic
files are the ones that have the same timestamp as the index
file's, because two file updates that sandwitch the index file
update must happen within the same second to trigger the
problem.

Since log message in a commit object is defined to be binary
blob, it could be something without an empty line between the
title line and the body text. Be careful to format such into
a form suitable for e-mail submission. There must be an empty
line between the headers and the body.

When I show transcripts to explain how something works, I often
find myself hand-editing the diff-raw output to shorten various
object names in the output.
This adds --abbrev option to the diff family, which shortens

This changes "pretty_print_string_list()" to show the git commands
alphabetically in column order, which is the normal one.
Ie instead of doing
git commands available in '/home/torvalds/bin'
----------------------------------------------
add am ...
applypatch archimport ...
cat-file check-ref-format ...
...
it does
git commands available in '/home/torvalds/bin'
----------------------------------------------
add diff-tree ...
am fetch ...
apply fetch-pack ...
...
where each column is sorted.
This is how "ls" sorts things too, and since visually the columns are much
more distinct than the rows, so it _looks_ more sorted.
The "ls" command has a "-x" option that lists entries by lines (the way
git.c used to): if somebody wants to do that, the new print-out logic
could be easily accomodated to that too. Matter of taste and preference, I
guess.

Currently the git "show commands" function will react to the environment
variable COLUMNS, or just default to a width of 80 characters.
That's just soo eighties. Nobody sane sets COLUMNS any more, unless they
need to support some stone-age software from before the age of steam
engines, SIGWINCH and TIOCGWINSZ.
So get with the new century, and use TIOCGWINSZ to get the terminal size.

Split out the functions that deal with the socketpair after
finishing git protocol handshake to receive the packed data into
a separate file, and use it in fetch-pack to keep/explode the
received pack data. We earlier had something like that on
clone-pack side once, but the list discussion resulted in the
decision that it makes sense to always keep the pack for
clone-pack, so unpacking option is not enabled on the clone-pack
side, but we later still could do so easily if we wanted to with
this change.

This removes the misguided attempt to refuse processing a branch
name xyzzy and insist it to be given as either heads/xyzzy or
tags/xyzzy when a tag xyzzy exists. There was no reason to do
so --- the search order was predictable and well defined, so if
the user says xyzzy we should have taken the tag xyzzy in such a
case without complaining.
This incidentally fixes another subtle bug related to this. If
such a duplicate branch/tag name happened to be a unique valid
prefix of an existing commit object name (say, "beef"), we did
not take the tag "beef" but after complaining used the commit
object whose name started with beef.
Another problem this fixes while introducing some confusion is
that there is no longer a reason to forbid a branch name HEAD
anymore. In other words, now "git pull . ref1:HEAD" would work
as expected, once we revert "We do not like HEAD branch" patch.
It creates "HEAD" branch under ${GIT_DIR-.git}/refs/heads (or
fast-forwards if already exists) using the tip of ref1 branch
from the current repository, and merges it into the current
branch.

git-am --skip does not unpack the next patch and ends up reapplying the
old patch, believing that it is the new patch in the sequence.
If the old patch applied successfully it will commit it with the
supposedly skipped log message and ends up dropping the following patch.
If the patch did not apply the user is left with the conflict he tried
to skip and has to unpack the next patch in the sequence by hand to get
git-am back on track.
By clearing the resume variable whenever skips bumps the sequence
counter we correctly unpack the next patch. I also added another
resume= in the case a patch file is missing from the sequence to
avoid the same problem when a file in the sequence was removed.

This makes git-check-ref-format fail for "HEAD". Since the check is only
executed when creating refs, the existing symbolic ref is safe.
Otherwise these commands, most likely are pilot errors, would do
pretty funky stuff:
