Well, I still don't like that though... Not only will it mess up the
completion output, but revision completion is also the most ressource
intense task: The script would have to recursively get all existing
versions, then get all revision for each version and finally concenate
them together.

The gain in typing speed is very little compared to the costs. One could
point out that listing all revisions might make it easier for the user
to remember/know which version he wants... But just listing all
revisions without any summary wont be a big help I think.

Another reason is that some commands (e.g. tla get) are also satisfied
with a version. So we should just do version completion if a revision is
a valid argument, maybe completing to base-0 or patch- if a version is
followed by two dashes.
