_But_, when running xemacs, backspace or delete hard suspends xemacs
and trash its terminal state.  Problem appears to be that in going to
raw mode, susp (and lots of other things) are set to ^?.  This isn't a 
problem from a local terminal, because the relevant keys don't
generate that code, but when coming in via ssh they do.

This feels like a bug in ncurses, with some things getting set to -1
(== \177 when masked) which shouldn't, but a fairly detailed look at
the ncurses sources doesn't reveal anything.

Any suggestions?
