Right, that was just for illustration.  I had spoken to someone who thought
that maybe vc-dir wasn't handling bzr shared repo directories correctly.

That won't be possible for me, since my $HOME is under bzr, and project
subdirs under that are of various vcses (including bzr, git, hg, and svn).

Is it possible to force vc-dir to use a specific vcs on invocation, or to
change vc-dir's backend after the fact?

If this bugs me enough, I'll take a crack at a workaround/fix.
