Title: Allow zero limit in Sort_InsertionLimited

Everywhere else seems to handle it fine, too.

I short circuited the open() instead of checking in the FILLING section as this operator already auto-closes. I have no objection to modifying the operator more deeply so that it doesn't auto-close at all (like the outstanding task wants to do for all operators).
