Subject: Restore more old Git completion behaviour.
X-Git-Url: http://git.iain.cx/?p=profile.git;a=commitdiff_plain;h=d8d037e261b3ca06605bde627110ca31cec8901e

Restore more old Git completion behaviour.

If we can't figure out a head print nothing rather than (unknown) as
this can get annoying when becoming other users and/or changing into
trees without permissions on the .git directory.
