Oh, lovely! I was *sure* I'd need to make git core changes for this, but
no, the precognitive powers of the git hackers had anticipated my needs
before I knew what they were!

(Now the only downside is gitweb's treatment of such heads: but looking
at the code, making it skip suitably formatted heads when displaying the
heads list is an utterly trivial one-liner.)
