Summary: a new bug in mactex.lisp

Initial Comment:
This bug was discovered by Kostas Oikonomou, who uses
the TeXmacs interface. But it is really a bug in
tex-mexpt. Just do this:

:lisp (tex '((mexpt) $a ((mminus) ((mplus) $b $c))) nil
nil 'mparen 'mparen)

and you get

(A ^ {-  B + C  })

The sum B+C is not in parenthes, though it should be.

To fix this bug, a simple change in mactex.lisp is
sufficient. In the function tex-mexpt, replace the line

(tex (cadr x) '("^ {- ")(cons " }" r) 'mparen 'mparen))

by the line

(tex (cadr x) '("^ {- ")(cons " }" r) 'mminus 'mparen))
