> Scratching my own itch, I've changed the code for repr_lincomb to
properly handle negative coefficients as well as zero. It required one
change to how coeff_repr works which may cause problems. I've included
testcases for repr_lincomb.
feel free to take over this patch if you like - I stopped working on it
since solving one issue somewhere caused others in other places.
To see if your patch causes problems somewhere, you cannot do much that
running the complete doctests...
Cheers, Christian
