--[[
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.
