It's true, but I don't think this is always actually a good tradeoff
for our users. A "unknown format" message is, I surmise from user
feedback, nearly as confusing and problematic as an error in opening
the branch reference. And it's likely to hit more people, either when
we make it a default, or when they fail to set relative paths and need
to upgrade.

We need to think about the larger issue but in this particular case I
think it may be reasonable to treat the old clients as just buggy for
not supporting it. We could presumably put a fix into 2.0.x to get it
to work?
