Yes. And if you use a lot of aliases, or a lot of machines with evolving 
aliases, the easiest way to inspect the alias is "git help <alias>". Not 
seeing it completed is an unexpected behavior.

Git is moving the right direction in terms of user-friendliness, e.g. by 
DWIMming "git checkout <remote branch>". Adding this completion would be 
a small step in the same direction, not more.
