D4426: zsh_completion: use revsets to exclude this rev from suggestions to hg merge

[av6 (Anton Shestakov)]

av6 added a comment.


  Now it's only one call to hg. All possible branches included, even if hg merge that-branch would complain (see my comment above), because in completions it's better to give extra suggestions than to miss some.
  
  But this "revision numbers + branch names" got me thinking, maybe it should also suggest hashes, since some people prefer them? Specifically, `{hash|shortest}`, so that it doesn't take too much space.
