a couple of errors in the manual for 5.13



I just built 5.13 and found a couple of problems in making 
doc/info/maxima.pdf:

1) In maxima.texi, @include category-macros.texi causes a 
problem, since category-macros.texi is not
included in the distribution.  So I commented it out.

2) In Trigonometric.texi, "@math{%pi...}"  should be changed 
to "@math{\pi...}", and "@math{%i}" to
"@math{i}", otherwise TeX complains loudly.

Perhaps these have been fixed in CVS?
