It would be a bit pointless without the second part. If we decide 
against it, list-branches is probably the better choice.

So I wonder what other people think.

Me neither, but... people do use tags to mark specific, *important* 
revisions. And supposedly check them out sometimes (maybe to see the 
exact code the "current production" version has?).

I do check out specific revisions sometimes too, but providing 
completion for that is fairly impossible. Completing tags seems like the 
next best thing.

Branches are most useful indeed.

I don't imagine having tags in there would really hurt, even if we don't 
pick them. IME tags usually follow a particular naming convention, so 
they won't interfere with completion.
