New description:

{{{

This works correctly on Maxima 5.26 - we need to upgrade! The new spkg is
at

Install the spkg and apply:

Replying to [comment:82 jdemeyer]:
> Replying to [comment:80 jpflori]:
> > IIRC there was a discussion some time ago on sae-devel about make a
one time huge patch for suppressing spaces but some people, especially
among sage-combinat, raised the problem that it would break patch queues
and that we should rather ensure that no such new lines where added and
fix for previous spaces made locally.
> For precisely this reason I would prefer not to just remove all spaces
everywhere. In code which is changed by the patch, it can be done. But
not just everywhere like this.
would it be OK if we just not apply the reviewer's patch?
