Thanks for the report and patch for this. Adding a new public interface
is the right way to do it.
I'm less certain about your second set of patches. This breaks backward
compatibility -- defined as what callers have come to expect -- in
several ways.
Philosophically, there should not be that much difference between a
function that accepts a `translated' key sequence and one that doesn't.
Even if a key sequence starts in an `untranslated' state, the caller
should be able to pass the translated version to rl_translate_keyseq
and have the result unchanged. It's an unusual key binding that can't
handle this, and I believe \C-@ is the only key sequence for which it
matters. None of the arrow key sequences in common use, for example,
contain it (that is your objection with _rl_term_ku, etc.).
Since I believe that for the most part `raw' key sequences such as those
in _rl_term_ku will pass through rl_translate_keyseq without modification,
I'm going to try the changes to rl_bind_keyseq_if_unbound_in_map and the
other changes in your second patch and see how it goes.
