[Maxima] [Maxima-commits] CVS: maxima/src simp.lisp,1.60,1.61

[Viktor T. Toth]

Sure, keep giving the poor programmer a hard time :-)

Actually, the change is a trivial bug fix, which I regression tested with
all four compilers that I have installed. With listarith=false, the list
code did things like [1,2]-[1,2] -> 0, which has the wrong dimensions. With
this change, we get [1,2]-[1,2] -> [0,0] even when listarith=false.

Um, for the record, I think that is not informative enough about the change.
I really have no idea what was changed or why, and it seems like
it might be important, since changing the way lists are handled
could break some programs.

FWIW
