Oh, I thought it made it more clear.  As a user of this function, I
basically just want to know if I need to put:

    :syntax-table foo-syntax-table

or
    :syntax-table 'foo-syntax-table

I'm fine with saying nothing, for the simple fact that these features
aren't used that much, and it's easy to just try both variants to see
which work.  But I think it would be better to say something if we can
come up with something clear.
