Well, POST to .bzr/smart can work when there's no .bzr/branch-format in
some cases, so I'm not sure that's right. e.g. consider something like
'bzr log $branch_url/README'. That said it's probably reasonable in
principle to try GET .bzr/branch-format before POST .bzr/smart, but I
fear it'll be pretty awkward in the existing code :/
