git log/diff: add -G<regexp> that greps in the patch text
Teach "-G<regexp>" that is similar to "-S<regexp> --pickaxe-regexp" to the
"git diff" family of commands. This limits the diff queue to filepairs
whose patch text actually has an added or a deleted line that matches the
given regexp. Unlike "-S<regexp>", changing other parts of the line that
has a substring that matches the given regexp IS counted as a change, as
such a change would appear as one deletion followed by one addition in a
patch text.
Unlike -S (pickaxe) that is intended to be used to quickly detect a commit
that changes the number of occurrences of hits between the preimage and
the postimage to serve as a part of larger toolchain, this is meant to be
used as the top-level Porcelain feature.
The implementation unfortunately has to run "diff" twice if you are
running "log" family of commands to produce patches in the final output
(e.g. "git log -p" or "git format-patch"). I think we _could_ cache the
result in-core if we wanted to, but that would require larger surgery to
the diffcore machinery (i.e. adding an extra pointer in the filepair
structure to keep a pointer to a strbuf around, stuff the textual diff to
the strbuf inside diffgrep_consume(), and make use of it in later stages
when it is available) and it may not be worth it.
The old text described the original design (one side does not have it at
all while the other side has it); this was later amended to check if the
number of occurrences changed, which is what we currently do with -S.

diff_tree(): Skip skip_uninteresting() when all remaining paths interesting
In 1d848f6 (tree_entry_interesting(): allow it to say "everything is
interesting" 2007-03-21), both show_tree() and skip_uninteresting() were
modified to determine if all remaining tree entries were interesting.
However, the latter returns as soon as it finds the first interesting path,
without any way to signal to its caller (namely, diff_tree()) that all
remaining paths are interesting, making these extra checks useless.
Pass whether all remaining entries are interesting back to diff_tree(), and
whenever they are, have diff_tree() skip subsequent calls to
skip_uninteresting().

entry matches one of the specified paths, but whether all remaining paths
will (or will not) match. When no paths are specified, all paths are

return 2 (all paths are interesting).
This will allow the caller to avoid calling tree_entry_interesting() again,

builtin/fetch.c: ignore merge config when not fetching from branch's remote
When 'git fetch' is supplied a single argument, it tries to match it
against a configured remote and then fetch the refs specified by the
named remote's fetchspec. Additionally, or alternatively, if the current
branch has a merge ref configured, and if the name of the remote supplied
to fetch matches the one in the branch's configuration, then git also adds
the merge ref to the list of refs to update.
If the argument to fetch does not specify a named remote, or if the name
supplied does not match the remote configured for the current branch, then
the current branch's merge configuration should not be considered.
git currently mishandles the case when the argument to fetch specifies a
GIT URL(i.e. not a named remote) and the current branch has a configured
merge ref. In this case, fetch should ignore the branch's merge ref and
attempt to fetch from the remote repository's HEAD branch. But, since
fetch only checks _whether_ the current branch has a merge ref configured,
and does _not_ check whether the branch's configured remote matches the
command line argument (until later), it will mistakenly enter the wrong
branch of an 'if' statement and will not fall back to fetch the HEAD branch.
The fetch ends up doing nothing and returns with a successful zero status.
Fix this by comparing the remote repository's name to the branch's remote
name, in addition to whether it has a configured merge ref, sooner, so that
fetch can correctly decide whether the branch's configuration is interesting
or not, and fall back to fetching from the remote's HEAD branch when
appropriate.
This fixes the test in t5510.

t/t5510: demonstrate failure to fetch when current branch has merge ref
When 'git fetch' is supplied just a repository URL (not a remote name),
and without a fetch refspec, it should fetch from the remote HEAD branch
and update FETCH_HEAD with the fetched ref. Currently, when 'git fetch'
is called like this, it fails to retrieve anything, and does not update
FETCH_HEAD, if the current checked-out branch has a configured merge ref.
i.e. this fetch fails to retrieve anything nor update FETCH_HEAD:
When 'git checkout' reports uncommitted changes, it also does so for
submodules.
The default mode is now to look really hard into submodules, not only
for different commits, but also for modified files. Since this can be
pretty expensive when there are a lot (and large) submodules, there is
the diff.ignoreSubmodules option.
Let's respect that setting when 'git checkout' reports the uncommitted
changes, since it does nothing else than a 'git diff --name-status'.

We start the pager too early for several git commands, which results in
the errors sometimes going to the pager rather than show up as errors.
This is often hidden by the fact that we pass in '-X' to less by default,
which causes 'less' to exit for small output, but if you do
export LESS=-S
you can then clearly see the problem by doing
git log --prretty
which shows the error message ("fatal: unrecognized argument: --prretty")
being sent to the pager.
This happens for pretty much all git commands that use USE_PAGER, and then
check arguments separately. But "git diff" does it too early too (even
though it does an explicit setup_pager() call)
This only fixes it for the trivial "git log" family case.

3) the buffer is indexed from top to bottom starting at
"data = buffer + entries * RABIN_WINDOW" and the multiplication
here does indeed overflows, making the resulting top of the buffer
much lower than expected.
This makes the number of actually produced index entries smaller than
what was computed initially, hence the assertion.
Furthermore, the current delta encoding format cannot represent offsets

detached-stash: introduce parse_flags_and_revs function
Introduce parse_flags_and_revs. This function requires that
there is at most one stash-like revision parameter and
zero or more flags.
It knows how to parse -q,--quiet and --index flags, but leaves
other flags parsed.
Specified revisions are checked to see that they are at
least stash-like (meaning: they look like something created
by git stash save or git stash create).
If this is so, then IS_STASH_LIKE is initialized to a non-empty value.
If the specified revision also looks like a stash log entry reference,
then IS_STASH_REF is initialized to a non-empty value.
References of the form ref@{spec} are required to precisely identify
an individual commit.
If no reference is specified, stash@{0} is assumed.
Once the specified reference is validated to be at least stash_like
an ensemble of derived variables, (w_commit, w_tree, b_commit, etc)
is initialized with a single call to git rev-parse.
Repeated calls to parse_flags_and_rev() avoid repeated calls
to git rev-parse if the specified arguments have already been
parsed.
Subsequent patches in the series modify the existing
git stash subcommands to make use of these functions
as appropriate.
An ensemble of supporting functions that make use of the state
established by parse_flags_and_rev(). These are described below:
The ancillary functions are:
is_stash_like(): which can be used to test
whether a specified commit looks like a commit created with
git stash save or git stash create.
assert_stash_like(): which can be used by
commands that misbehave unless their arguments stash-like.
is_stash_ref(): which checks whether an argument
is valid stash reference(e.g. is of the form
['refs/']stash['@{'something'}])
assert_stash_ref(): which can be used by commands
that misbehave unless their arguments are both stash-like and
refer to valid stash entries.
