What I want is

(defun string-data-p (str)
  (and (stringp str)
       (not (string= str "")) ))

Is it a string?

Does it have data?

nil and "" is (here) just as useless.

But the funny thing is, my "empty-string-p" looked like
`string-empty-p', that's why I replaced the calls to that
instead. Then everything broke. So I guess it didn't look
quite like that after all...
