(ok, author looks better, but committer doesn't obey the AUTHOR_ vars yet)

This might not be how you intended git fork to behave, but without doing _something_ to protect the head parameter a bit, this is just asking for a corrutped .git/HEAD file.

commit 76faec069dfeae59c3ce5faaad10bdcded0cc908 tree c291316b28eff4042c80850cd93445345a606835 parent 1cdbc0a19b8d9b68f1f42735e2f14f1289823a63 author Brad Roberts <braddr@puremagic.com> 1113738584 -0700 committer Brad Roberts,,, <braddr@gameboy2> 1113738584 -0700

gitfork needs to normalize the optional third parameter before using it.
