OK, let's close it.

This because `describe-theme-1` is not looping in buffer to find
`deftheme` definition.

Try (describe-theme 'leuven) to reproduce (if not already loaded of course).

This patch fixes it:

+                (when (eq (car-safe sexp) 'deftheme)

     (princ "\n\nDocumentation:\n")
     (princ (if (stringp doc)
 	       (substitute-command-keys doc)

However for the modus themes it will fail as well because deftheme is
nested inside a eval-when-compile.

And while I am at it, the docstring of Leuven-dark is wrong (guess it has
been copy/pasted from Leuven without modifications).
