We block SIGINT and SIGQUIT while the editor runs so that
git is not killed accidentally by a stray "^C" meant for the
editor or its subprocesses. This works because most editors
ignore SIGINT.
However, some editor wrappers, like emacsclient, expect to
die due to ^C. We detect the signal death in the editor and
properly exit, but not before writing a useless error
message to stderr. Instead, let's notice when the editor was
killed by a terminal signal and just raise the signal on
ourselves. This skips the message and looks to our parent
like we received SIGINT ourselves.
The end effect is that if the user's editor ignores SIGINT,
we will, too. And if it does not, then we will behave as if
we did not ignore it. That should make all users happy.
Note that in the off chance that another part of git has
ignored SIGINT while calling launch_editor, we will still
properly detect and propagate the failed return code from
the editor (i.e., the worst case is that we generate the
useless error, not fail to notice the editor's death).

SIGINT and SIGQUIT are not generally interesting signals to
the user, since they are typically caused by them hitting "^C"
or otherwise telling their terminal to send the signal.

The user's editor likely catches SIGINT (ctrl-C). but if
the user spawns a command from the editor and uses ctrl-C to
kill that command, the SIGINT will likely also kill git
itself (depending on the editor, this can leave the terminal
in an unusable state).
Let's ignore it while the editor is running, and do the same
for SIGQUIT, which many editors also ignore. This matches
the behavior if we were to use system(3) instead of
run-command.

The launch_editor function uses the convenient run_command_*
interface. Let's use the more flexible start_command and
finish_command functions, which will let us manipulate the
parent state while we're waiting for the child to finish.

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR
of the superproject. A later "git submodule add $path" to add a
different submodule at the same path will fail. Diagnose this case
a bit better, and if the user really wants to add an unrelated
submodule at the same path, give the "--name" option to give it a
place in $GIT_DIR of the superproject that does not conflict with
the original submodule.

"git rm submodule" cannot blindly remove a submodule directory as
its working tree may have local changes, and worse yet, it may even
have its repository embedded in it. Teach it some special cases
where it is safe to remove a submodule, specifically, when there is
no local changes in the submodule working tree, and its repository
is not embedded in its working tree but is elsewhere and uses the
gitfile mechanism to point at it.
* jl/submodule-rm:
submodule: teach rm to remove submodules unless they contain a git directory

You can override an option set in the LESS variable by simply prefixing

t9200 defines $CVSROOT where cvs should init its repository
$CVSROOT is set to $PWD/cvsroot.
cvs init is supposed to create the repository inside $PWD/cvsroot/CVSROOT
"cvs init" (e.g. version 1.11.23) checks if the last element of the path is
"CVSROOT", and if a directory with e.g. $PWD/cvsroot/CVSROOT already exists.
For such a $CVSROOT cvs refuses to init a repository here:
"Cannot initialize repository under existing CVSROOT:
On a case insenstive file system cvsroot and CVSROOT are the same directories
and t9200 fails.
Solution: use $PWD/tmpcvsroot instead of cvsroot $PWD/cvsroot

AddressSanitizer (http://clang.llvm.org/docs/AddressSanitizer.html)
complains of a one-byte buffer underflow in parse_name_and_email() while
running the test suite. And indeed, if one of the lines in the mailmap
begins with '<', we dereference the address just before the beginning of
the buffer when looking for whitespace to remove, before checking that
we aren't going too far.
So reverse the order of the tests to make sure that we don't read
outside the buffer.

git pull --rebase does some clever tricks to find the base
for $upstream, but it forgets that we may not have any
branch at all. When this happens, git merge-base reports its
"usage" help in the middle of an otherwise successful
rebase operation, because git-merge is called with one too
few parameters.
Since we do not need the merge-base trick in the case of a
detached HEAD, detect this condition and bypass the clever
trick and the usage noise.

This saves us some code, but it also reduces the number of
processes we start for each filtered commit. Since we can
parse both author and committer in the same sed invocation,
we save one process. And since the new interface avoids tr,
we save 4 processes.
It also avoids using "tr", which has had some odd
portability problems reported with from Solaris's xpg6
version.
We also tweak one of the tests in t7003 to double-check that
we are properly exporting the variables (because test-lib.sh
exports GIT_AUTHOR_NAME, it will be automatically exported
in subprograms. We override this to make sure that
filter-branch handles it properly itself).

The only ident-parsing function we currently provide is
get_author_ident_from_commit. This is not very
flexible for two reasons:
1. It takes a commit as an argument, and can't read from
commit headers saved on disk.
2. It will only parse authors, not committers.
This patch provides a more flexible interface which will
parse multiple idents from a commit provide on stdin. We can
easily use it as a building block for the current function
to retain compatibility.

You can currently set the output format to --short or
--porcelain. There is no --long, because we default to it
already. However, you may want to override an alias that
uses "--short" to get back to the default.
This requires a little bit of refactoring, because currently
we use STATUS_FORMAT_LONG internally to mean the same as
"the user did not specify anything". By expanding the enum
to include STATUS_FORMAT_NONE, we can distinguish between
the implicit and explicit cases. This effects these
conditions:
1. The user has asked for NUL termination. With NONE, we
currently default to turning on the porcelain mode.
With an explicit --long, we would in theory use NUL
termination with the long mode, but it does not support
it. So we can just complain and die.
2. When an output format is given to "git commit", we
default to "--dry-run". This behavior would now kick in
when "--long" is given, too.
