Can anyone reproduce this? This is a build from the 22 branch, with
`mac-option-modifier' set to `meta'.
What I can reproduce is holding down M-n: when input just once, it
just brings up an echo area message saying that it's not bound. But
when held down (which causes the input to repeat), it'll input the
tilde dead key (˜) just like when the option modifier is passed to
the system.
NB Switching off `mac-input-method-mode' (a patch in Aquamacs)
doesn't change anything, and the problem shows up in a (Carbon) build
straight from the GNU Emacs CVS as well. But I can't reproduce the M-
v problem.
