OK, I see now: caps-mode should be fixed to use last-command-event
instead of (the now deleted) last-command-char.

And the problem with overwrite mode is that caps-mode doesn't pay
attention to overwrite-mode, it always inserts a character, even if
overwrite-mode is on.

So it's a bug in caps-mode: its caps-mode-self-insert-command should
be smarter, and pay attention to overwrite-mode.
