Based on what Stefan said (see below), if the region (regular or
rectangular) is active, `backward-delete-char-untabify' deletes the
*region* instead of a single character. I interpreted that to mean
that, if Edit -> Clear is only enabled when there's an active
region/rect, `backward-delete-char-untabify' is equivalent to a
hypothetical `delete-rect-or-region'. Maybe that's not so simple, and
there's a variable I'm not aware of that can alter its behavior to not
delete the region (or some other problem). In any case, mapping Edit
-> Clear to a command that knows how to delete a rectangular region
might be helpful.
