How to avoid ^- in maxima output? (Leo Butler) [Martin Kraska]

Leo,

we think, that we can ask the user to install the latest maxima release, because this might be a plausible request for them. Insofar your proposal sounds reasonable 

We perhaps won't ask the users to mess around in the maxima installation. In our understanding that would mean sacrificing user's convenience for the sake of our convenience. We also do not think that it is a good idea that we mess around in the maxima repository, things might go wrong there.

Thus we ask you to include the code in the next maxima release and accept a temporary perhaps non-GPL compliant state until the next windows release of maxima is available.

Martin.
