When threaded grep is in effect, the patterns are duplicated and
recompiled for each thread. Avoid "--debug" output during the
recompilation so that the output is given once instead of "1+nthreads"
times.

Our "grep" allows complex boolean expressions to be formed to match
each individual line with operators like --and, '(', ')' and --not.
Introduce the "--debug" option to show the parse tree to help people
who want to debug and enhance it.
Also "log" learns "--grep-debug" option to do the same. The command
line parser to the log family is a lot more limited than the general
"git grep" parser, but it has special handling for header matching
(e.g. "--author"), and a parse tree is valuable when working on it.
Note that "--all-match" is *not* any individual node in the parse
tree. It is an instruction to the evaluator to check all the nodes
in the top-level backbone have matched and reject a document as
non-matching otherwise.

When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.
At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

If stderr isn't a tty, we shouldn't be printing incremental progress
messages. In particular, this affects 'git checkout -f . >&logfile'
unless you provided -q. And git-new-workdir has no way to provide -q.
It would probably be better to have progress.c check isatty(2) all the time,
but that wouldn't allow things like 'git push --progress' to force progress
reporting to on, so I won't try to solve the general case right now.
Actual fix suggested by Jeff King.

When reading patterns from a file, we pass the lines as allocated string
buffers to append_grep_pat() and never free them. That's not a problem
because they are needed until the program ends anyway.
However, now that the function duplicates the pattern string, we can
reuse the strbuf after calling that function. This simplifies the code
a bit and plugs a minor memory leak.

In abe1998 ("git checkout -b: allow switching out of an unborn
branch"), a code-path overly-optimisticly assumed that a
branch-name was specified. This is not always the case, and as
a result a NULL-pointer was attempted printed to .git/HEAD.
This could lead to at least two different failure modes:
1) vsnprintf formated the NULL-string as something useful (e.g
"(null)")
2) vsnprintf crashed
Neither were very convenient for formatting a new HEAD-reference.
To fix this, reintroduce some strictness so we only take this
new codepath if a banch-name was specified.

The options are declared as a static global, but really they

When we show a reflog selector (e.g., via "git log -g"), we
perform some DWIM magic: while we normally show the entry's
index (e.g., HEAD@{1}), if the user has given us a date
with "--date", then we show a date-based select (e.g.,
HEAD@{yesterday}).
However, we don't want to trigger this magic if the
alternate date format we got was from the "log.date"
configuration; that is not sufficiently strong context for
us to invoke this particular magic. To fix this, commit
f4ea32f (improve reflog date/number heuristic, 2009-09-24)
introduced a "date_mode_explicit" flag in rev_info. This
flag is set only when we see a "--date" option on the
command line, and we a vanilla date to the reflog code if
the date was not explicit.
Later, commit 8f8f547 (Introduce new pretty formats %g[sdD]
for reflog information, 2009-10-19) added another way to
show selectors, and it did not respect the date_mode_explicit
flag from f4ea32f.
This patch propagates the date_mode_explicit flag to the
pretty-print code, which can then use it to pass the
appropriate date field to the reflog code. This brings the
behavior of "%gd" in line with the other formats, and means
that its output is independent of any user configuration.

The send_pack function gets a "progress" flag saying "yes,
definitely show progress" or "no, definitely do not show
progress". This gets set properly by transport_push when
send_pack is called directly.
However, when the send-pack command is executed separately
(as it is for the remote-curl helper), there is no way to
tell it "definitely do this". As a result, we do not
properly respect "git push --no-progress" for smart-http
remotes; you will still get progress if stderr is a tty.
This patch teaches send-pack --progress and --no-progress,
and teaches remote-curl to pass the appropriate option to
override send-pack's isatty check. This fixes the
--no-progress case above, and as a bonus, also makes "git
push --progress" work when stderr is not a tty.

The send_pack_args struct has two verbosity flags: "quiet"
and "progress". Originally, if "quiet" was set, we would
tell pack-objects explicitly to be quiet, and if "progress"
was set, we would tell it to show progress. Otherwise, we
told it neither, and it relied on isatty(2) to make the
decision itself.
However, commit 01fdc21 changed the meaning of these
variables. Now both "quiet" and "!progress" instruct us to
tell pack-objects to be quiet (and a non-zero "progress"
means the same as before). This works well for transports
which call send_pack directly, as the transport code copies
transport->progress into send_pack_args->progress, and they
both have the same meaning.
However, the code path of calling "git send-pack" was left
behind. It always sets "progress" to 0, and thus always
tells pack-objects to be quiet. We can work around this by
checking isatty(2) ourselves in the cmd_send_pack code path,
restoring the original behavior of the send-pack command.

git-gc executes many sub-commands. The argument list for
some of these is constant, but for others we add more
arguments at runtime. The latter is implemented by allocating
a constant extra number of NULLs, and either using a custom
append function, or just referencing unused slots by number.
As of commit 7e52f56, which added two new arguments, it is
possible to exceed the constant number of slots for "repack"
by running "git gc --aggressive", causing "git gc" to die.
This patch converts all of the static argv lists to use
argv-array. In addition to fixing the overflow caused by
7e52f56, it has a few advantages:
1. We can drop the custom append function (which,
incidentally, had an off-by-one error exacerbating the
static limit).
2. We can drop the ugly magic numbers used when adding
arguments to "prune".
3. Adding further arguments will be easier; you can just
add new "push" calls without worrying about increasing
any static limits.

Since 88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.
Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.
Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

When we pack everything into one big pack with "git repack
-Ad", any unreferenced objects in to-be-deleted packs are
exploded into loose objects, with the intent that they will
be examined and possibly cleaned up by the next run of "git
prune".
Since the exploded objects will receive the mtime of the
pack from which they come, if the source pack is old, those
loose objects will end up pruned immediately. In that case,
it is much more efficient to skip the exploding step
entirely for these objects.
This patch teaches pack-objects to receive the expiration
information and avoid writing these objects out. It also
teaches "git gc" to pass the value of gc.pruneexpire to
repack (which in turn learns to pass it along to
pack-objects) so that this optimization happens
automatically during "git gc" and "git gc --auto".
