Deleting a tag from a bound branch

There are sorta two problems with it; one is a generalization of that
one, in that you can't make a tag without a new rev, which is kinda
icky (and also means you can never tag the head of a branch.  At
least, not without a custom script dug into bzrlib to let you hardcode
your new revid...).

The other is that it's a layering violation, to have to extract a
working tree file to find out what revision in the branch we're
referring to (and the subsidiary question of "Hey, which rev of the WT
are we supposed to look at the file from?").  Fun.
