Setting CURLOPT_HTTPHEADER doesn't add HTTP headers, but replaces whatever
set of headers was configured before, so setting to NULL doesn't have any
magic meaning, and is pretty much useless when setting to another list

When a downloaded ref doesn't contain a sha1, the error message displays
a random sha1 because of uninitialized memory. This happens when cloning
a repository that is already a clone of another one, in which case
refs/remotes/origin/HEAD is a symref.

The configuration reader to enumerate branches that have configuration

After tentatively applying a patch from a contributor, you can get a
replacement patch with corrected code and unusable commit log message.
In such a case, this sequence ought to give you an editor based on the
message in the earlier commit, to let you describe an incremental
improvement:

    git reset --hard HEAD^ ;# discard the earlier one
    git am <corrected-patch
    git commit --amend -c HEAD@{1}

Unfortunately, --amend insisted reusing the message from the commit
being amended, ignoring the -c option.  This corrects it.

Previously, git-svn would ignore cases where the path we're
tracking is removed from the repository.  This was to prevent
heads with follow-parent from ending up with a tree full of
empty revisions (and thus breaking rename detection).

The previous behavior is fine until the path we're tracking
is re-added later on, leading to the old files being merged
in with the new files in the directory (because the old
files were never marked as deleted)

We will now only remove all the old files locally that were
deleted remotely iff we detect the directory we're in is being
created from scratch.

Thanks for Marcus D. Hanwell for the bug report and
Peter Baumann for the analysis.

Because we feed the changed filenames to CVS on the command
line, it was possible for massive commits to overflow the
system exec limits. Instead, we now do an xargs-like split
of the arguments.

This means that we lose some of the atomicity of calling CVS
in one shot. Since CVS commits are not atomic, but the CVS
protocol is, the possible effects of this are not clear;
however, since CVS doesn't provide a different interface,
this is our only option for large commits (short of writing
a CVS client library).

The argument size limit is arbitrarily set to 64kB. This
should be high enough to trigger only in rare cases where it
is necessary, so normal-sized commits are not affected by
the atomicity change.

This implements earlier Linus's optimization to trim common lines at the
end before passing them down to low level xdiff interface for all of our
xdiff users.

We could later enhance this to also trim common leading lines, but that
would need tweaking the output function to add the number of lines
trimmed at the beginning to line numbers that appear in the hunk
headers.

When recording a merge that conflicted and ends up in no changes after
manual resolution, commit callchain looked like this:

	cmd_commit() ->
            prepare_log_message() ->
                run_status() ->
		    wt_status_print()

This invocation of run_status() is asked to find out if there is a
committable change, but it unconditionally gave instructions such as
"use git-add" at the same time.  When in merge, we do allow an empty
change to be recorded, so after showing this message the code still went
ahead and made a commit.

This introduces "nowarn" parameter to run_status() to avoid these
useless messages.  If we are not allowed to create an empty commit, we
already call run_status() again in the original codepath, and the
message will be shown from that call anyway.

The "-z" format is all about machine parsability, but showing renamed
paths as "common/{a => b}/suffix" makes it impossible.  The scripts would
never have successfully parsed "--numstat -z -M" in the old format.

This fixes the output format in a (hopefully minimally) backward
incompatible way.

 * The output without -z is not changed.  This has given a good way for
   humans to view added and deleted lines separately, and showing the
   path in combined, shorter way would preserve readability.

 * The output with -z is unchanged for paths that do not involve renames.
   Existing scripts that do not pass -M/-C are not affected at all.

 * The output with -z for a renamed path is shown in a format that can
   easily be distinguished from an unrenamed path.

This is based on Jakub Narebski's patch.  Bugs and documentation typos
are mine.
