Summary: Patch for mactex.lisp

Initial Comment:
`tex' does not translate `and', `or', `not' and `#' to
valid TeX expressions.  Currently we get this:

tex('(a # b));   =>  $$a # b$$
tex('(a and b)); =>  $$a(\and)b$$
tex('(a or b));  =>  $$a(\or)b$$
tex('(not a));   =>  $$\not a$$

Which are all invalid.

`\not', `\and', `\or' and `#' should be replaced with
`\neg', `\land', `\lor' and `\ne'.  Additionally `or'
and `and' should be tex-infix not tex-nary.

After applying the attached patch we get this:

tex('(a # b));   =>  $$a\ne b$$
tex('(a and b)); =>  $$a\land b$$
tex('(a or b));  =>  $$a(\lor )b$$
tex('(not a));   =>  $$\neg\,a$$

The parens in `or' still aren't quite right, but at
least it's valid TeX.
