Ah, yes, that's annoying.  I agree that we should kill the *Backtrace*
buffer -- the current code just empties the buffer, but leaves it
behind, which doesn't seem useful.

(`q' aka `bury-buffer' commonly in many modes, well, buries the buffer,
but in this case we empty it first, so it's not useful to avoid killing
it in this case.)
