Transport.has itself can be quite flaky on http.  Perhaps calling rmdir
a second time, and asserting that it raises NoSuchFile?

We use the assert family, so assertFalse would be preferable here.

This bzrlib/transport/__init__.py change looks spurious (and not PEP8):

Does your plugin open all http branches, or does it use the plain http
handlers for non WebDAV urls?  Probably doesn't matter much.  The point
is to test that for readonly operations, directories aren't used, so as
long as the readonly transport is also under test, we should be okay.

Could you please not name your branch bzr.webdav/trunk?  The last
element of the name should be unique to your project, because that's the
default name used in various places.  Ideally, the last element would be
the plugin name, i.e. "bzr/webdav" as in "bzrlib.plugins.webdav".
"trunk/bzr.webdav" or "bzr.webdav.trunk" would also be fine.

It's probably a good idea to call Server.__init__ in here (it may do
something, someday).
