The new option -p instructs git grep to print the previous function
definition as a context line, similar to diff -p. Such context lines
are marked with an equal sign instead of a dash. This option
complements the existing context options -A, -B, -C.
Function definitions are detected using the same heuristic that diff
uses. User defined regular expressions are not supported, yet.

Factor out pre context line handling into the new function
show_pre_context() and change the algorithm to rewind by looking for
newline characters and roll forward again, instead of maintaining an
array of line beginnings and ends.
This is slower for hits, but the cost for non-matching lines becomes
zero. Normally, there are far more non-matching lines, so the time
spent in total decreases.

Print a hunk mark before matches from a new file are shown, in addition

When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many. Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one. 'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:
count + (*argcp - 1) + 1
Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

The following invocations did not work as expected on Windows:
git mv foo\bar dest
git mv foo\ dest
The first command was interpreted as
git mv foo/bar dest/foo/bar
because the Windows style directory separator was not obeyed when the
basename of 'foo\bar' was computed.
The second command failed because the Windows style directory separator was
not removed from the source directory, whereupon the lookup of the
directory in the index failed.
This fixes both issues by using is_dir_sep() and basename().

I do various statistics on git, and one of the things I look at is merges,
because they are often interesting events to count ("how many merges vs
how much 'real development'" kind of statistics). And you can do it with
some fairly straightforward scripting, ie
git rev-list --parents HEAD |
grep ' .* ' |
git diff-tree --always -s --pretty=oneline --stdin |
less -S
will do it.
But I finally got irritated with the fact that we can skip merges with
'--no-merges', but we can't do the trivial reverse operation.
So this just adds a '--merges' flag that _only_ shows merges. Now you can
do the above with just a
git log --merges --pretty=oneline
which is a lot simpler. It also means that we automatically get a lot of
statistics for free, eg
git shortlog -ns --merges
does exactly what you'd want it to do.

Cleanup the documentation to explicitly state that --exclude-directory
is only meaningful when used with -u. Also make the documentation more
consistent with the usage message printed with read-tree --help-all.
The -m, --prefix, --reset options are performing similar actions
(setting some flags, read_cache_unmerged(), checking for illegal option
combinations). Instead of performing these actions when the options are
parsed, we delay performing them until after parse-opts has finished.
The bit fields in struct unpack_trees_options have been promoted to full

When providing a list of paths to limit what is exported, the object that
a tag points to can be filtered out entirely. This new switch allows
the user to specify what should happen to the tag in such a case. The
default action, 'abort' will exit with an error message. With 'drop', the
tag will simply be omitted from the output. With 'rewrite', if the object
tagged was a commit, the tag will be modified to tag an alternate commit.
The alternate commit is determined by treating the original commit as the
"parent" of the tag and then using the parent rewriting algorithm of the
revision traversal machinery (related to the "--parents" option of "git
rev-list")

The code expects a ref name to be provided in commit->util. While there
was some code to set commit->util, it only worked in cases where there was
an unbroken chain of revisions from a ref to the relevant commit. In
cases such as running
git fast-export --parents master -- COPYING
commit->util would fail to be set. The old method of setting commit->util
has been removed in favor of requesting show_source from the revision
traversal machinery (related to the "--source" option of "git log" family
of commands.)
However, this change does not fix cases like
git fast export master~1
or
git fast export :/arguments
since in such cases commit->util will be "master~1" or ":/arguments" while
we need the actual ref (e.g. "refs/heads/master")
