Format the categories with the appropriate sort key. CATEGORIES is a list of
categories.
-- LANG is an object encapsulating a language; if nil, the object for
language code 'und' (undetermined) will be used.
-- SORT_KEY is placed in the category invocation, and indicates how the
page will sort in the respective category. Normally this should be nil,
and a default sort key based on the subpage name (the part after the
colon) will be used.
-- SORT_BASE lets you override the default sort key used when SORT_KEY is
nil. Normally, this should be nil, and a language-specific default sort
key is computed from the subpage name (e.g. for Russian this converts
Cyrillic ё to a string consisting of Cyrillic е followed by U+10FFFF,
so that effectively ё sorts after е instead of the default Wikimedia
sort, which (I think) is based on Unicode sort order and puts ё after я,
the last letter of the Cyrillic alphabet.
-- FORCE_OUTPUT forces normal output in all namespaces. Normally, nothing
is output if the page isn't in the main, Appendix:, Reconstruction: or
Citations: namespaces.
-- SC is a script object; if nil, the default will be used from the sort
base.
