Comment (by stumpc5):
I updated the patch on the combinat queue and also uploaded it here. The
negative entries test was accidentally fixed in the following patch on
reflection groups rather than in this patch. I replaced all {{{asserts}}}
by {{{ValueErrors}}} (since I was told that's the way to do it some time
ago).
As said, Hugh: feel free to take it over, or to review it as is.
Best, Christian
