Re: [PATCH] use child_process_init() to initialize struct child_process variables

I peeked at libgit2 and I think it does not support bundles at all yet,
so that is safe. Grepping for "bundle" in dulwich turns up no hits,
either.

Looks like JGit does support them. I did a very brief test, and it seems
to silently ignore a HEAD ref that has the NUL (I guess maybe it just
rejects it as a malformed refname).

We could make JGit happier either by:

  1. Only including the symref magic in ambiguous cases, so that regular
     ones Just Work as usual.

  2. Including two lines, like:

        $sha1 HEAD\0symref=refs/heads/master
	$sha1 HEAD

     which JGit does the right thing with (and git.git seems to, as
     well).

Sounds sensible, even though it looks ugly X-<.
