Summary: FIx c-h on OS X

Initial Comment:
I'm not sure if this is portable, but...

I've been trying to install zile on OS X.

The 2.2.22 release can't tell the difference between ^h and backspace - 
both are treated as backspace.

The patch below fixes things in Terminal.app on OS X, but I haven't tested 
elsewhere.

Looking in curses.h I see:

#define KEY_BACKSPACE   0407            /* backspace key */

Looking in the Terminal config I don't have any special binding for
backspace.

This isn't a bug in Zile, it's a question of how Terminal is set up (and
possibly curses.h). Can you find out for me how KEY_BACKSPACE is defined in
curses.h. Your patch messes things up because KEY_BACKSPACE should do
"backspace", not "Ctrl-H". I believe that you can ensure that Terminal
sends Ctrl+? when you press Backspace, rather than Ctrl-H, which is
possibly what is happening at present.

Sorry I took so long to read this; I've taken steps to ensure I don't
overlook patches in future.
