std bug in Spielwiese

Description

Hello,

in Spielwiese I get a wrong answer for std for the following example:

ring r = integer,(v,w,t),dp; ideal J = 2v, wt, vt-3v; std(J);

_[1]=2v _[2]=wt _[3]=vt-3v

The output seems wrong, because (w*v) is missing ( S( wt, vt-3v) = 3wv )

This seems to be fixed in the newest spielwiese version available on github:
