> Stefan, is our current documentation of :predicate incomplete?

I'm not really familiar with that argument (AFAICT it was implemented
by Lars in commit b8b18cf34a04a).  The whole feature puts me off a bit
because of its name: in my world a "predicate" is a kind of function,
so I think it's a poor name for a variable containing some list-based
description of a set of modes.

But indeed, it seems the docstring forgets to mention that the
`:predicate MODES` argument causes the introduction of a new variable
called `MINOR-MODE-predicate` and whose default value is MODES.


        Stefan "who'd rename the `:predicate` arg to something like
                `:modes` and the `MODE-predicate` variable to something
                like `MODE-modes`."
