The first two work without issues for me:

> hg up "a a"                                     
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
> hg up "a,a"                                     
1 files updated, 0 files merged, 0 files removed, 0 files unresolved

and the third one simply isn't accepted in the first place:

> hg branch "a:a"                                 
abort: ':' cannot be used in a name

What version of mercurial are you using? And are you using weird plugins
which may break things?
