There's a deleted answer on Programmers where the option to undelete has a number beside it:
When I mouse over the (1), the tooltip says
2 more vote(s) needed to undelete this question
I think it should say "this answer" (or "this post") instead. And while I'm at it, I think it should also say "restore" instead of "undelete" to be consistent with the "vote to restore this post" tooltip.
