"git reflog expire" (and "git gc") examines the reflog entries and
discards old/stale ones using two criteria. The entries that are older
than "reflogexpire" (defaults to 90 days) are unconditionally removed, and
the entries that are older than "reflogexpireunreachable" (defaults to 30
days) are removed if the entry point at commits that are not reachable
from the value of the ref.
This is reasonable for local branches, remote tracking branches and tags.
You (or other people) may have failed experiments that have been made and
then later discarded by resetting the tip of the branch back, and setting
the value of "reflogexpireunreachable" shorter than that of "reflogexpire"
will prune the entries that describe these failed experiments earlier than
the entries that describe the steps that led to the current history.
It however doesn't make much sense for "HEAD" reflog. When you switch
between branches, it is normal that the tip of the branch you were on is
not an ancestor of the branch you have switched to. The moral equivalent
of expiring failed experiments in per-branch reflog for "HEAD" reflog is
to expire entries that talk about commits that cannot be reached from any
ref.

Two more tests that sleep only to waste tick can be converted to use
test_tick and take expiry parameters relative to $test_tick. The basic
idea is to replace "sleep 1" with "test_tick" to cause the "time" to pass.
These tests are interested in expiring things with "now" as the timestamp,
soo use a timestamp relative to $test_tick to give them more stability and
reproducibility.

The destination name within the object store is easily computed
on demand, reusing a static buffer held by sha1_file.c. We don't
need to copy the entire path into the request structure for safe
keeping, when it can be easily reformatted after the download has
been completed.
This reduces the size of the per-request structure, and removes
yet another PATH_MAX based limit.

The description for core.autocrlf refers to reads from / writes to
"the filesystem", the only use of this rather ambiguous term, which
technically could be referring to the git object database. (All other
mentions are part of phrases such as "..filesystems (like NFS)..").
Other sections, including the section on core.safecrlf, use the term
"work tree" for the same purpose as the term "the filesystem" is used in
the core.autocrlf section, so that seems like a good alternative, which
makes it clearer what direction the addition/removal of CR characters
occurs in.

Consider an evil merge of two commits A and B, both of which have a
file 'foo', but the merge result does not have that file.
The combined-diff code learned in 4462731 (combine-diff: do not punt
on removed or added files., 2006-02-06) to concisely show only the
removal, since that is the evil part and the previous contents are
presumably uninteresting.
However, to diagnose an empty merge result, it overloaded the variable
that holds the file's length. This means that the check also triggers
for truncated files. Consequently, such files were not shown in the
diff at all despite the merge being clearly evil.
Fix this by adding a new variable that distinguishes whether the file
was deleted (which is the case 4462731 handled) or truncated. In the
truncated case, we show the full combined diff again, which is rather
spammy but at least does not hide the evilness.

v1.7.0-rc0~18^2 (branch -d: base the "already-merged" safety on the
branch it merges with, 2009-12-29) taught ‘git branch’ a new heuristic
for when it is safe to delete a branch without forcing the issue. It
is safe to delete a branch "topic" without second thought if:
- the branch "topic" is set up to pull from a (remote-tracking,
usually) branch and is fully merged in that "upstream" branch, or
- there is no branch.topic.merge configuration and branch "topic" is
fully merged in the current HEAD.

"git am -3" first tries to apply the patch without any extra trick, and
applies it to a synthesized tree for 3-way merge after the first attempt
fails. "git apply" exits with status 1 for a patch that is well-formed
but is not applicable (and it dies on other errors with non-zereo, non-1
status) and has an optimization to fall back to the 3-way merge only in
the case.
An earlier patch 3ddd170 (am: suppress apply errors when using 3-way,
2009-06-16) squelched diagnostic messages from the first attempt, not to
be shown to the end user. This worked reasonably well if the reason the
first application failed was because the patch was made against a wrong
version.
When the patch is corrupt (e.g. line-wrapped or leading whitespaces got
dropped), however, because the second patch application is not even
attempted, the error message from the first application is never shown
and is forever lost. This message is necessary to locate where the patch
is corrupt and fix it up.
We could fix this issue by reverting 3dd170, or keeping the error message
to somewhere and showing it, but because this is an error codepath, the
easiest is to disable the optimization. The second patch application is
attempted even when the input is corrupt, and it will notice, diagnose,
and stop with an error message.

This teaches the --color-words engine a more general interface that
supports two new modes:
* --word-diff=plain, inspired by the 'wdiff' utility (most similar to
'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+}
* --word-diff=porcelain, which generates an ad-hoc machine readable
format:
- each diff unit is prefixed by [-+ ] and terminated by newline as
in unified diff
- newlines in the input are output as a line consisting only of a
tilde '~'
Both of these formats still support color if it is enabled, using it
to highlight the differences. --color-words becomes a synonym for
--word-diff=color, which is the color-only format. Also adds some
compatibility/convenience options.

If more than one annotated tag points at the same commit, use the
tag whose tagger field has a more recent date stamp. This resolves
non-deterministic cases where the maintainer has done:
$ git tag -a -m "2.1-rc1" v2.1-rc1 deadbeef
$ git tag -a -m "2.1" v2.1 deadbeef
If the tag is an older-style annotated tag with no tagger date, we
assume a date stamp at the UNIX epoch. This will cause us to prefer
an annotated tag that has a valid date.
We could also try to consider the tag object chain, favoring a tag
that "includes" another one:
$ git tag -a -m "2.1-rc0" v2.1-rc1 deadbeef
$ git tag -a -m "2.1" v2.1 v2.1-rc1
However traversing the tag's object chain looking for inclusion
is much more complicated. Its already very likely that even in
these cases the v2.1 tag will have a more recent tagger date than
v2.1-rc1, so with this change describe should still resolve this
by selecting the more recent v2.1.
