Thank you for the hint.

If I see it right, path_rel(b, r) does a subset of
expand_filename(path_concat(b, r)), as long as b is an absolute pathname
(starts with "/"). (otherwise the pwd is prepended.)

However, the examples should work with standard commands as well

   Color_Scheme_Path+= "," + path_concat(path_dirname(__FILE__), "colors");

   variable hsjmode_dir= path_concat(path_dirname(__FILE__), "/hsjmode/");

is a nice trick indeed. (I recommend to put it at the end of the mode, so it
will only be executed if the rest has loaded successfully.)

May your words come true...
