--[=[
	This module implements the headword templates {{ru-noun}}, {{ru-adj}},
	{{ru-adv}}, {{ru-noun+}}, etc. The main entry point is show(), which is
	meant to be called from one of the above templates. However, {{ru-noun+}}
	uses the entry point noun_plus(), and {{ru-noun-m}} (not currently used)
	uses the entry point noun_multi(). When calling show(), the first parameter
	of the #invoke call is the part of speech. Other parameters are taken from
	the parent template call.

	The implementations for different types of headwords (different parts of
	speech) are set in pos_functions[POS] for a given POS (part of speech).
	The value is a 2-argument function of (ARGS, DATA):
	-- ARGS on entry is initialized to the parent template call's arguments,
	   with blank arguments converted to nil.
	-- DATA on entry is initialized to a table, with entries like this:
		local data = {lang = lang, pos_category = poscat_th, categories = {}, heads = {}, translits = {}, genders = {}, inflections = {}}
	   where:
	   -- LANG is an object describing the language.
	   -- POS_CATEGORY is the (plural) part of speech, e.g. "คำนาม" or "verbs".
	   -- CATEGORIES on entry is a list of categories. There will be one category
		  corresponding to the part of speech (e.g. [[Category:Russian adverbs]]),
		  and possibly additional categories such as [[Category:Requests for accents in Russian entries]]
		  and [[Category:Russian terms with irregular pronunciations]]. On exit
		  it may contain additional categories to place the page in.
	   -- HEADS on entry is a list of the headwords, taken directly from arguments
		  '1', 'head2', 'head3', ...
	   -- TRANSLITS on entry is a list of translits, matching one-to-one with
		  heads in HEADS, or nil if no manual translit was specified.
	   -- GENDERS on entry is an empty list. On exit it should be the appropriate
		  gender settings, and will be passed directly to full_headword() in
		  [[Module:headword]]. See the documentation for that module for info on
		  the format of this setting.
	   -- INFLECTIONS on entry is an empty list. On exit it should be the
		  appropriate inflections to be displayed in the headword, and will be
		  passed directly to full_headword() in [[Module:headword]]. See the
		  documentation for that module for info on the format of this setting.

-- Convert {RUSSIAN, TR} in `form` into an "inflection object" of the form needed for one of the inflection parts in

--    target = "|head= USED IN {{head}} OR SIMILAR", translit = "|tr= USED IN {{head}} OR SIMILAR"}
-- Normally, `target` in the accelerator object is handled automatically and taken from the displayed text of the link,
-- but this doesn't work in comparative forms, where the form reads e.g. "([[покраснее|по]])[[краснее|красне́е]]" but we
-- want the target to be just красне́е. So we always specify the target and translit, but default it to the form and its
-- translit unless the `target` parameter is passed in. Note also that we don't specify translit="TRANSLIT" in the
-- outer (inflection) object because then the translit will be displayed in the headword inflection.
--
-- `data` is used to fetch the values of `lemma` and `lemma_translit` in the accelerator object and to add a "Requests
-- for accents" category if the form is missing accents. (FIXME: Consider throwing an error instead.) `pos` is the
-- part of speech of the lemma and is used for naming the "Requests for accents" category. `accel_form` goes in the
-- accelerator object; if nil, no accelerator object is specified. `accel_pos` is the part of speech of the inflection,
-- if different from the lemma, and goes in the accelerator object. `target` is used to populate the `target` and
-- `translit` fields in the accelerator object and is the form used to check for missing accents; in both cases it
-- defaults to `form` if omitted.
