Subject: [PATCH 1/2] pathspec magic: add '^' as alias for '!'

The choice of '!' for a negative pathspec ends up not only not matching
what we do for revisions, it's also a horrible character for shell
expansion since it needs quoting.

So add '^' as an alternative alias for an excluding pathspec entry.
