Applied, committed and pushed.

Aha, yeah, the trouble is that usher was originally built to handle
the distinction between different sub-servers by hostname only, and
you use the same hostname for all of them.  I did make a change so it
would accept several stanzas with the same hostname, but it seems I
didn't look closely enough at the the rest of the code, so you're
currently stuck with having to separate the sub-servers at a hostname
level.

I have the same goal as you, to have sub-servers differentiated by
branch patterns as well as hostnames, so I'll take a closer look in a
few days and see what can be done with it.

Hmm, well, since usher is just a communication proxy of sorts, I see
that as a minor problem unless it introduces corruption into the
network streams.  I'll parrot Nathaniel here by saying "patches
welcome!" :-)

Cheers,
