Proposed patch attached. I've boldly defaulted the functionality to
enabled, but we can flip that if people feel strongly about it. I
documented it in the lisp reference manual, but we can put it in the
user manual as well.

Don't write key sequences directly in documentation strings. Instead,
use the @address@hidden construct to stand for them. For example,
