  Not a good way to do it, with the control character embedded. Instead
the following may be used, which also avoids a problem with use of ^ in
sh.

	stty erase '\^H' echoe
                    ^^^  ^^^^^
                     |     |_ this forces the character to be erased
                     |_______ three characters, *not* cntl-H

  I think the key is the need for echoe.
