run_command() returns a single integer specifying either an
error code or the exit status of the spawned program. The
only way to tell the difference is that the error codes are
outside of the allowed range of exit status values.
Rather than make each caller implement the test against a
magic limit, let's provide a macro.

When run_command() was asked to run a non-existant command, its behavior
varied depending on the platform:
- on POSIX systems, we would fork, and then after the execvp call
failed, we could call die(), which prints a message to stderr and
exits with code 128.
- on Windows, we do a PATH lookup, realize the program isn't there, and
then return ERR_RUN_COMMAND_FORK
The goal of this patch is to make it clear to callers that the specific
error was a missing command. To do this, we will return the error code
ERR_RUN_COMMAND_EXEC, which is already defined in run-command.h, checked
for in several places, but never actually gets set.
The new behavior is:
- on POSIX systems, we exit the forked process with code 127 (the same
as the shell uses to report missing commands). The parent process
recognizes this code and returns an EXEC error. The stderr message is
silenced, since the caller may be speculatively trying to run a
command. Instead, we use trace_printf so that somebody interested in
debugging can see the error that occured.
- on Windows, we check errno, which is already set correctly by
mingw_spawnvpe, and report an EXEC error instead of a FORK error
Thus it is safe to speculatively run a command:
int r = run_command_v_opt(argv, 0);
if (r == -ERR_RUN_COMMAND_EXEC)
/* oops, it wasn't found; try something else */
else
/* we failed for some other reason, error is in r */

There is a static function called run_command which
conflicts with the library function in run-command.c; this
isn't a problem currently, but prevents including
run-command.h in git.c.
This patch just renames the static function to something
more specific and non-conflicting.

v1.6.1 introduced ".have" extension to the protocol to allow the receiving
side to advertise objects that are reachable from refs in the repositories
it borrows from. This was meant to be used by the sending side to avoid
sending such objects; they are already available through the alternates
mechanism.
The client side implementation in v1.6.1, which was introduced with
40c155f (push: prepare sender to receive extended ref information from the
receiver, 2008-09-09) aka v1.6.1-rc1~203^2~1, were faulty in that it did
not consider the possiblity that the repository receiver borrows from
might have objects it does not know about.
This fixes it by refraining from passing missing commits to underlying
pack-objects. Revision machinery may need to be tightened further to
treat missing uninteresting objects as non-error events, but this is an
obvious and safe fix for a maintenance release that is almost good enough.

The comment in parentheses is wrong, as one has to leave out both the
colon and <dst>. This situation is covered by the section a few lines
down:
A parameter <ref> without a colon pushes the <ref> from the source
repository to the destination repository under the same name.
So, just remove the parentheses.

builtin-fsck: fix off by one head count

builtin-commit.c: do not remove COMMIT_EDITMSG

According to the man page, if "git fsck" is passed one or more heads, it
should verify connectivity and validity of only objects reachable from the
heads it is passed.
However, since 5ac0a20 (Make builtin-fsck.c use parse_options.,
2007-10-15) the command behaved as if no heads were passed, when given
only one argument.

The function lock_remote() sends MKCOL requests to make leading
directories; However, if it does not put a forward slash '/' at the end of
the path, the server sends a 301 redirect.
By leaving the '/' in place, we can avoid this additional step.
Incidentally, at least one version of Curl (7.16.3) does not resend
credentials when it follows a 301 redirect, so this commit also fixes
a bug.

When getting the result of remote_ls(), we were advancing the variable
"path" to the relative path inside the repository.
However, then we went on to malloc a bogus amount of memory: we were
subtracting the prefix length _again_, quite possibly getting something
negative, which xmalloc() interprets as really, really much.

git-commit tries to remove the file ./COMMIT_EDITMSG instead of
$GIT_DIR/COMMIT_EDITMSG after commit preparation (e.g. running
hooks, launching editor).
This behavior exists since f5bbc3225c4b07 "Port git commit to C".
Some test cases (e.g. t/t7502-commit.sh) rely on the existence of
$GIT_DIR/COMMIT_EDITMSG after committing and, I guess, many people
are used to it. So it is best not to remove it.
This patch just removes the removal of COMMIT_EDITMSG.
