OK, let me try to clarify.  When I say "applications" I mean things like R,
python, and gdb that use Readline for editing.  I thought that the problem
was a reluctance by the maintainers of these applications to change their
code to deal with readline changes, or mismatches in updates so that
readline gets changed before the calling applications change to match it.
If that's not a problem, in your view, then an application-settable
variable that is tested in rl_callback_read_char is probably the right
place to solve it.
