Bug #143529 says comment links are busted with regards to their tooltips, that's fine, it is removing them. But it would be handy to have something there. For comment links, this should be the commenter and comment time. This information should be accessible in some form on show_bug. The harder bit would be the combo comment/bug links. Ideally you would get the comment tooltip followed by the bug tooltip. But how can you compute the comment number of another bug? It is not stored on the comments (I think), so you'd need to pull all of the comments of that other bug. But if we did do all this, we could probably do some of the nice things we do for bug links on comment links and combo links, non-existence checking for example.
