Seems ok to me ! I Applied it, used it, and did not understand why it was not possible already !

By the way, I added some docstrings to the function, so if you think it is ok.. ;-)

The patch multinomial_list.patch contains some badly formatted docstrings. But those shouldn't prevent the patch from being merged. Better to fix those formatting issues in a separate ticket. See #6845 for a follow up to fix this docstring issue.

While merging and testing these patches:

I ran into a doctest failure:

This has nothing to do with the above patches. Strangely, it crops up when I run the test on sage.math. But the test passes on mod.math and geom.math. Merged patches in this order:

1. 12846.patch
2. trac_6819-reviewer.patch
