A minor improvement has been made to the system:  the behavior of the
backspace character has been made smarter.  Instead of just backspacing
your terminal past the character it is erasing, it now actually blanks
the character off the screen.  Note, however, that it doesn't do this
quite correctly for tabs, backslashes (\), and invisible characters --
the oddities involved in backspacing over them remain, although in a
slightly different form.

Printing terminals will behave a bit oddly, since they can't actually
blank out a character once they have printed it, but the oddness should
not be harmful and the net result on them will be the same as it was
before:  the erased character and the new one overprinted.

If this behavior causes real trouble for anybody, arrangements can be
made to turn it off for specific users.  See David or me.
