All Emacs tags start with "emacs-", so if you just input any other 
character and press TAB, you won't see the tags.

I think we should consider whether it's likely to be a problem, and not 
just reject the unlikely options. Because other people's workflows can 
be different.

And I do anticipate having to check out a particular release version, 
someday.

Further, like Artem reminded us, we already have a revisions completion 
table. So the attached patch seems preferable to me. WDYT?
