If I run vc-dir on a directory /foo/bar/baz, where /foo/.bzr and
/foo/bar/.git exist, then Emacs guesses wrongly that /foo/bar/baz is
under Bzr.
It seems that first, the directory is not registered with a backend
(which may be on purpose, since git does not actually register
directories?), but then secondly that /foo is checked before /foo/bar
when deciding which backend to use.
Further, deleting the .bzr directory (which was indeed bogus; it’s
obviously relatively rare to have a tree under one VCS inside a tree
under another, with the exception of foreign modules, possibly?) did not
help: I had to restart Emacs to get it to forget the .bzr directory.

This is the documented way it works, for the time being at least.
This is basically a duplicate of

Thanks for the pointer. To describe the current behavior as
"documented" is stretching things, though (at least, I had to trawl
through the code to get a handle on what was going on, and I can see
no documentation cited in the thread above or in the docstrings that
describes the current behavior).
In any case, documented or not, it's a bug, and it's a bug in the
stable version of Emacs, not just the development version.
