Have you computed this with a version in which the newest changes of Adi and me had been merged?

We had been working on precisely this issue, but up to now the pull-request is still in the review process. (The chosen behaviour of mstd for this situation is:

write the original generators into the second entry, if this set is smaller than the standard basis, otherwise put the standard basis into the second entry)
