[MERGE] revised revert help text

[John Yates]

What happens if I do the following?

[[ edit A -> A.1 ]]
[[ edit B -> B.1 ]]

bzr commit

[[ edit A -> A.2 ]]
[[ edit C -> C.1 ]]

bzr commit
bzr revert A B

I think that it is intuitive that I should end up with B.1.  But
what about A?  Should I get A.1 or A.2?

This points up a hole in the bzr UI.  While I can use revert to
chain backward through the subset of revisions in which a given
file was modified the is no revision spec that provides access
to a simple numbering of those revisions that modified that file.
