Bug#713071: More information on the maxima-doc bug

forwarded 713071 maxima at math.utexas.edu
thanks

Just a note I looked into this briefly -- there is some error in the
maxima_index.lisp generation starting with the first anchor in
maxima-2.info (equalp) -- the offset output to the index is off by one,
and every index thereafter points to the previous anchor.

Take care,
