[issue20630] Add sorting helpers for collections containing None values

[Tim Peters]

Tim Peters added the comment:

I've haven't yet seen anyone complain about the inability to compare None except in the specific context of sorting.  If it is in fact specific to sorting, then this specific symptom and "the problem" are in fact the same thing ;-)
