Update of /cvsroot/maxima/maxima/tests In directory sc8prcvs16.sourceforge.net:/tmp/cvsserv23186/tests Modified Files: rtestsum.mac Log Message: Simplify definite summations to explicit sums (i.e. expressions with operator = "+") only if the simpsum flag is true. This restores the behaviour of Maxima previous to the revisions of December 2005 when it was changed inadvertently in this respect.
