Definitely the merge of multi-tty code, the same problem has been
reported in the trunk multiple times.
macterm.c is missing a call to add_keyboard_wait_descriptor (see xterm.c
and w32term.c), which was necessary to get input working at all on
Windows after the multi-tty merge. Despite this being pointed out
several times, noone who is using a Mac has tried adding this call and
reported back whether it solves the problem.

I think reverting the change is correct, as the old mule based utf
codings are no longer used internally, but it might be a good idea to
find what the change was in the trunk that caused this code to be
merged, as there may be something there that should be changed in the
unicode branch as well.
