But it's used with in-first-directory in
in-user-configuration-directory:
(defun in-user-configuration-directory (x &key (direction :input))
"return pathname under user configuration directory, subpathname X"
(in-first-directory (user-configuration-directories) x
:direction direction))
hence the problem.
