The revision.c options-parser will parse "--first-parent"
for us, but the blame code does not actually respect it, as
we simply iterate over the whole list returned by
first_scapegoat(). We can fix this by returning a
truncated parent list.
Note that we could technically also do so by limiting the
return value of num_scapegoats(), but that is less robust.
We would rely on nobody ever looking at the "next" pointer
from the returned list.
Combining "--reverse" with "--first-parent" is more
complicated, and will probably involve cooperation from
revision.c. Since the desired semantics are not even clear,
let's punt on this for now, but explicitly disallow it to
avoid confusing users (this is not really a regression,
since it did something nonsensical before).

Both "git show-ref -h" and "git show-ref --help" illustrated that the
"--exclude-existing" option makes the command read list of refs
from its standard input. Change only the "show-ref -h" output to
have a pair of "<>" around the placeholder that designate an input
file, i.e. "git show-ref --exclude-existing < <ref-list>".

Ensure that when passing a pipe, the gnulib poll replacement will not
return 0 before the timeout has passed.
Not obeying the timeout (and merely returning 0) causes pathological
behavior when preparing a packfile for a repository and taking a
long time to do so. If poll were to return 0 immediately, this would
cause keep-alives to get sent as quickly as possible until the packfile
was created. Such deviance from the standard would cause megabytes (or
more) of keep-alive packets to be sent.
GetTickCount is used as it is efficient, stable and monotonically
increasing. (Neither GetSystemTime nor QueryPerformanceCounter have
all three of these properties.)

Currently, git-svn parses an authors file using the perl regex
/^(.+?|\(no author\))\s*=\s*(.+?)\s*<(.+)>\s*$/
in order to extract svn user name, real name and e-mail.
This does not match an empty e-mail field like "<>". On the other hand,
the output of an authors-prog is parsed with the perl regex
/^\s*(.+?)\s*<(.*)>\s*$/
in order to extract real name and e-mail.
So, specifying a trivial file grep such as
grep "$1" /tmp/authors | head -n 1 | cut -d'=' -f2 | cut -c'2-'
as the authors prog gives different results compared to specifying
/tmp/authors as the authors file directly.
Instead, make git svn uses the perl regex
/^(.+?|\(no author\))\s*=\s*(.+?)\s*<(.*)>\s*$/
for parsing the authors file so that the same (slightly more lenient)
regex is used in both cases.

f8da6801 (am --skip: support skipping while on unborn branch,
2015-06-06) introduced a performance regression to "git am --skip",
where it used "read-tree" to reconstruct the index from scratch
without reusing the cached stat information.
This is a backport of the corresponding patch to the builtin am in 2.6:
3ecc704 (am --skip/--abort: merge HEAD/ORIG_HEAD tree into index,
2015-08-19).
Reportedly, it can make a huge difference on Windows, in one case a `git
rebase --skip` took 1m40s without, and 5s with, this patch.

Recent "git am" had regression when adding a Signed-off-by line

am: match --signoff to the original scripted version
When executing user-specified programs, we generally always
want to use a shell, for flexibility and consistency. One
big exception is executing $GIT_SSH, which for historical
reasons must not use a shell.
Once upon a time the logic in git_connect looked like:
if (protocol == PROTO_SSH) {
... setup ssh ...
} else {
... setup local connection ...
conn->use_shell = 1;
}
But over time the PROTO_SSH block has grown, and the "local"
block has shrunk so that it contains only conn->use_shell;
it's easy to miss at the end of the large block. Moreover,
PROTO_SSH now also sometimes sets use_shell, when the new
GIT_SSH_COMMAND is used.
Let's just set conn->use_shell when we're setting up the "conn"
struct, and unset it (with a comment) in the historical GIT_SSH
case. This will make the flow easier to follow.

Linus noticed that the recently reimplemented "git am -s" defines
the trailer block too rigidly, resulting in an unnecessary blank
line between the existing sign-offs and his new sign-off. An e-mail
submission sent to Linus in real life ends with mixture of sign-offs
and commentaries, e.g.

patch here
Because the reimplementation reused append_signoff() helper that is
used by other codepaths, which is unaware that people intermix such
comments with their sign-offs in the trailer block, such a message
was judged to end with a non-trailer, resulting in an extra blank
line before adding a new sign-off.
The original scripted version of "git am" used a lot looser
definition, i.e. "if and only if there is no line that begins with
Signed-off-by:, add a blank line before adding a new sign-off". For
the upcoming release, stop using the append_signoff() in "git am"
and reimplement the looser definition used by the scripted version
to use only in "git am" to fix this regression in "am" while
avoiding new regressions to other users of append_signoff().
In the longer term, we should look into loosening append_signoff()
so that other codepaths that add a new sign-off behave the same way
as "git am -s", but that is a task for post-release.

When we "switch" to another local repository to run the server
side of a fetch or push, we must clear the variables in
local_repo_env so that our local $GIT_DIR, etc, do not
pollute the upload-pack or receive-pack that is executing in
the "remote" repository.
We have never done so for ssh connections. For the most
part, nobody has noticed because ssh will not pass unknown
environment variables by default. However, it is not out of
the question for a user to configure ssh to pass along GIT_*
variables using SendEnv/AcceptEnv.
We can demonstrate the problem by using "git -c" on a local
command and seeing its impact on a remote repository. This
config ends up in $GIT_CONFIG_PARAMETERS. In the local case,
the config has no impact, but in the ssh transport, it does
(our test script has a fake ssh that passes through all
environment variables; this isn't normal, but does simulate
one possible setup).

Since the commit a3da882120 (pager: do wait_for_pager on signal
death), we call wait_for_pager() in the pager's signal handler. The
recent bug report revealed that this causes a deadlock in glibc at
aborting "git log" [*1*]. When this happens, git process is left
unterminated, and it can't be killed by SIGTERM but only by SIGKILL.
The problem is that wait_for_pager() function does more than waiting
for pager process's termination, but it does cleanups and printing
errors. Unfortunately, the functions that may be used in a signal
handler are very limited [*2*]. Particularly, malloc(), free() and the
variants can't be used in a signal handler because they take a mutex
internally in glibc. This was the cause of the deadlock above. Other
than the direct calls of malloc/free, many functions calling
malloc/free can't be used. strerror() is such one, either.
Also the usage of fflush() and printf() in a signal handler is bad,
although it seems working so far. In a safer side, we should avoid
them, too.
This patch tries to reduce the calls of such functions in signal
handlers. wait_for_signal() takes a flag and avoids the unsafe
calls. Also, finish_command_in_signal() is introduced for the
same reason. There the free() calls are removed, and only waits for
the children without whining at errors.
