I fixed the tabs and a couple other trivial things in
lp:~mnordhoff/loggerhead/serve-config.

However, now there's a different issue: When serving branches on a
remote transport, trying to access .bzr/ results in a
TooManyConcurrentRequests traceback from the
BzrDir.open_containing_from_transport() call in check_is_a_branch().

E.g.:

serve-config$ bzr serve --directory .. &
serve-config$ ./serve-branches bzr://localhost/ &
serve-config$ bzr log -r -1 http://localhost:8080/serve-config/
