bzr info shows DeprecationWarning when WT at rev.0 and out of date

[Alexander Belchenko]

I have branch with tree on my central bzr server. Actually it should be treeless branch, because I don't use trees on the server. I've only pushed there via bzr:// protocol, so WT never was updated and stuck at revno.0.

Doing `bzr info -v` I've got DeprecationWarning. I think it's a bug (as an user I'm not interesting in such sort of warnings in my info). T: is network mapped drive of my server files area:

T:\repo\branch>bzr info -v

It is a bug, and it probably just needs a trivial update to that line in branch.py.
