Replying to SimonKing:
I just found that the documentation (at least with #9976 applied) is not good. Some stuff is included that certainly does not belong there.
Actually, on second thought, it belongs there: I am talking about the two singular_function instances included in the module. The main problem was that singular_function includes the documentation provided by Singular without taking care of formatting -- resulting in numerous errors (e.g., back ticks are misinterpreted as the beginning of Latex expressions, the indentation is handled differently, and so on).
In #11268, I suggest to take care if it by turning the Singular documentation into a verbose code block. With that change, the documentation looks a lot better. I therefore make it a new dependency.
Depends on #11068 #11268
