The "* <pgm>" convention

Because of problems such as the one GLS mentioned with "* <pgm>", 
MACSYMA opted for ".ALL. <pgm>" instead.  I think that using "*" 
here is much more trouble than it is worth.  (Witness some of the 
problems LISP has had with it e.g. wrt OPEN.)  I think that the 
semantics of "*" and "all" are really different, they are really 
different kinds of wildcards and two different conventions should 
be used.
