Robey Pointer, and lo! it spake thus:

That's my feeling.

% bzr tag -r78 FOO
% bzr tag --delete FOO
% bzr tag --move -r79 FOO
% bzr tag --list

Those all seem pretty self explanatory.  The only obvious ambiguity is
whether "bzr tag FOO" would tag the head of the tree or the currently
checked-out rev.  Commiting tags, or `bzr showtag` and `bzr movetag`
and `bzr settag` and family, just make me twitch.  I'm slowly moving
stuff into bzr instead of into tla for a _reason_!
