Re: S-backspace

[Richard Stallman <rms@gnu.org>]

    It would be nice if <S-backspace> was bound to the same function as <backspace>.
    When i type in all upper-case letters (e.g. some macro name) i often press
    <S-backspace> to fix a typo, not <backspace>. I think it would be a sane default
    binding.

When an upper case function key character has no binding, Emacs looks
for a binding for the corresponding unshifted character.  However,
there was a bug in the case of backspace.

This patch seems to fix it.  But I am not sure it is right.
The meaning of the start and end fields in a keyremap are
not documented and I am not sure what is the right thing to do
to them here.

Stefan, could you check this is correct, and document those fields?
