I don't pretend to understand all the underlying goo of keyboard
handling in XEmacs, but I do undesstand that XEmacs doesn't convert
incoming X keyboard events into any charset elements.  Backspace and
Delete are just that, Backspace and Delete.  Notably, `C-h' and
Backspace are not at all the same thing.

Under X, XEmacs distinguishes between the concepts of <tab>, `C-i',
and `C-<tab>'.  There is no charset analogue to this; taken as mere
ASCII charset elements, a <tab> is already a "controllified" `I'
(which is to say, the control characters are those for which the upper
3 bits have been zeroed).

Within a terminal environment, including an xterm, XEmacs is of course
limited to the set of key events that survive xterm's massaging of the
X event stream into an ASCII stream -- `C-<tab>' is indeed identical
to <tab> is identical to `C-i'.
