maxima source, allegro, pathnames, also clearwindow()

loading the new maxima-package.lisp  fixes a number of
things, but the search paths for files are still not set up
right.  Even after hacking init-cl.lisp so that the path names
do not have the c:\\/... prefix, the parsing of pathnames in
allegro seems to differ from that in the other lisps. The separation
of the combined suffix values doesn't seem to happen. 

Also
some functions  (see  demo/demo.dem ...) do not seem to work
when I force maxima to read them.  For example, clearscreen()
says Error cant clear window, and goes into a break loop.
This is a problem  in XMaxima 5.9.0  as well.


Here's a problem...
(C4) batch("demo.dem")
;

Could not find `demo.dem' using paths in FILE_SEARCH_MAXIMA (combined 
values:

[C:/.maxima/###.{mac,mc}, 
c:/maxima/maxima-5.9.0/share/maxima/5.9.0/{share,sha#

re/algebra,share/calculus,share/combinatorics,share/contrib,share/diffequation#

 -- an error.  Quitting.  To debug this try DEBUGMODE(TRUE);)
(C5) demo(demo);
