Well, I've put it into aba, and it's been quite handy.  Putting it into 
tla proper would probably entail getting most commands to use new 
functions for picking revisions.

In my input validation work, I've noticed that pretty well every command 
that accepts either a version or a revision has its own implementation 
of determining the revision of a version.

It wouldn't hurt to unify the processing by providing an 
"arch_determine_revision ()" command in cmdutils that validated the 
version/revision, checked if the supplied version/revision existed, and 
determined the latest revision if the version was supplied.

That way, there's always decent input validation, and less duplicate 
code.  Maybe we could add alias expansion there.  Maybe we could make 
patchlevels always refer to the tree-version at the same time.
