The above situation seems rather silly (and unlikely); if `foo-extra' screws
around like that, then I don't think we should expect custom to intuit what
the right thing to do is.  If a hook overrode the binding, on the other hand,
then I think restoring to A is the _right_ thing to do (the custom command is
probably `restore to original setting').

... which is a misnomer, since it's not really `100%', just 90% with a
different 10% cut out.
