-<P>Returns non-zero if the file is a directory. If the
-filename ends in a directory seperator (usually the 
-slash '/'), the existence of the directory will not
-be verified and '1' is returned. This is much faster
-than <tt>fl_filename_isdir</tt> if the file is known
-to exist, because its filename was obtained via
-<tt>fl_filename_list</tt> or similar.
