I'd hope that bzr places no restrictions on what the user wants to do with
it; I really hate that the 'version' component of an arch branch name
doesn't let you use alphas in it...  so I think that a --tag option being
separate to -r is a good idea (i.e. rev numbers only for -r and tag names
only for tag)

That sounds good; suggestions on how to name tags to avoid conflicts is best
left as a best-practice rather than enforced by the tool.
