It is, but changing this is a problem.  I can easily modify the code so
that it handles keymap[key].type == ISKMAP and behaves appropriately, but
it introduces an incompatibility.  ESC is one of the characters that
terminates an incremental search; making this change will break that.  I'm
reluctant to change the behavior as a result.
