#569 mactex ignores aliases / FIX
Mactex ignores aliases; here is an example
(%i1) ordergreat(a);
(%o1) DONE
(%i2) tex(a);
$$_101a\leqno{\tt NIL}$$
(%o2) NIL
(%i3) build_info();
Maxima version: 5.9.0.1cvs
Maxima build date: 12:29 5/12/2004
host type: i686-pc-mingw32
lisp-implementation-type: Kyoto Common Lisp
lisp-implementation-version: GCL 2.7.0
Here is one way fix this bug; change tex-atom to
(defun tex-atom (x l r) ;; atoms: note: can we lose by
leaving out {}s ?
(if (symbolp x) (setq x (or (get x 'reversealias) x)))
(append l
(list (cond ((numberp x) (texnumformat x))
((and (symbolp x) (get
x 'texword)))
((stringp x) (tex-string x))
((characterp x) (tex-char x))
(t (tex-stripdollar x))))
r))
Testing ...
(%o3)
(%i4) load("c:/maximacvs/maxima/src/mactex.lisp");

(%i5) tex(a);
$$a\leqno{\tt NIL}$$
(%o5) NIL

Ordergreat isn't all that useful, but it is a good way to
change the ordering of an expression to something more
standard for typesetting.

Is there a reason not to apply this fix?

I can't think of any reason to not apply it---I've used
the patch a few times to help tidy tex output. For
this purpose, it doesn't work all that well. Say I want
all x's before y's. Using ordergreat works in a sum, but
not in a product
(%i1) x+y+x*y;
(%o1) x y + y + x
(%i2) ordergreat(x,y,z);
(%o2) done
(%i3) x+y+x*y;
(%o3) y x + x + y
(The funny \leqno{\tt ...} stuff in my first posting was due to
a mactex bug that is no longer with us, I think).

I've pasted (if (symbolp x) (setq x (or (get x 'reversealias) x))) into TEX-ATOM and the result seems to work as expected. Committed as r1.58 src/mactex.lisp.
