Many other GUI applications beep under some circumstances that need
user attention.

Maybe we should simply revisit the places where we bitch-at-user, and
remove the beep from some of them.

But I don't see anything bad in beeping under extreme circumstances,
and don't support disabling it entirely.

The problem is, without the beep, the screen sometimes does not change
at all.  And that is BAD, from the HE point of view, at least IMO.
