Git is just weird (there).

I'm hesitant to add this without auth. What I'd like to have myself is
a way for people to say "the repository has changed, please look at
$otherurl until the next upload". Requesting a re-clone would be a
similar action. I might look into adding auth support via dacs, though
that would take some time unless someone else gets onto it.

Nak.

I'm specifically not shortcutting http access via ssh because I want
to trap errors like "no git update-server-info was run". Now, just
fetching the HEAD info via ssh would work, but that'd be a gross hack.

Nod. I'll look into this.

LSREMOTE=$(git ls-remote ...)
HEADREF=$(echo "$LSREMOTE" | grep ...)

Well it is actually a shell script disguised as Perl, so that wouldn't
matter much ;)

I'll get onto it over the next days. Thanks for the prod, I had though
I'd fixed this.
