`keywordp' is to exclude keywords. Those are not
special forms like "defun", or even "if", but instead
:foreground, :bold, anything that starts with a colon.
`boundp' will always eval to t for those, as they are
bound to their names.
Perhaps it makes sense to exclude those, as those
aren't variables, for sure.
But this is possible
(defvar :var-looks-like-keyword)
though further assignment is not (?).
So I don't think I'll add that. It doesn't hurt to have
it say that :bold is :bold.
