Right, but I'd rather the additional keys followed the same format as
in the above-mentioned patch by Stefan, posted in bug#13839, because
that is what we have in xterm.el nowadays.

I'm not sure I understand how you can programmatically generate a list
of keys: wouldn't it still involve a manually-maintained list at some
level?
I think just adding the missing combinations is a better way forward.
Thanks.
