More importantly, it is for dumb protocol transports, not for gitweb.

You forgot to mention that you fixed the last place that directly used "$GIT" to invoke the command, bypassing sub git_cmd. That is a consistency clean-up worth mentioning.

I would rather do:

	m|^([0-9a-f]{40})\srefs/($type/?[^^]+)|

which would catch both space and tab.
