[PATCH] completion: fix completing unstuck email alias arguments

Completing unstuck form of email aliases doesn't quite work:

  $ git send-email --to <TAB>
  alice   bob     cecil
  $ git send-email --to a<TAB>
  alice   bob     cecil

While listing email aliases works as expected, the second case should just complete to 'alice', but it keeps offering all email aliases instead.

The cause for this behavior is that in this case we mistakenly tell __gitcomp() explicitly that the current word to be completed is empty, while in reality it is not. As a result __gitcomp() doesn't filter out non-matching aliases, so all aliases end up being offered over and over again.

Fix this by not passing the current word to be completed to __gitcomp() and letting it go the default route and grab it from the '$cur' variable. Don't pass empty prefix either, because it's assumed to be empty when unspecified, so it's not necessary.
