	 * Convert from the nominative form of a noun to other cases.
	 * Invoked with {{GRAMMAR:case|word}} inside messages.
	 *
	 * case is a sequence of words, each of which is case insensitive.
	 * Between words, there must be at least one space character.
	 * Only the 1st character of each word is considered.
	 * Word order is irrelevant.
	 *
	 * Possible values specifying the grammatical case are:
	 *	1, Nominative
	 *	2, Genitive
	 *	3, Dative
	 *	4, Accusative, -omitted-
	 *
	 * Possible values specifying the article type are:
	 *	Betoont               focussed or stressed article
	 *	-omitted-             unstressed or unfocussed article
	 *
	 * Possible values for the type of genitive are:
	 *	Sing, Iehr            prepositioned genitive = possessive dative
	 *	Vun, Fon, -omitted-   postpositioned genitive
	 *	                               = preposition "vun" with dative
	 *
	 * Values of case overrides & prepositions, in the order of preceedence:
	 *	Sing, Iehr            possessive dative = prepositioned genitive
	 *	Vun, Fon              preposition "vun" with dative
	 *	                                     = postpositioned genitive
	 *	En, em                preposition "en" with dative
	 *
	 * Values for object gender specifiers of the possessive dative, or
	 * prepositioned genitive, evaluated with "Sing, Iehr" of above only:
	 *	Male                  a singular male object follows
	 *	-omitted-             a non-male or plural object follows
	 *
	 * We currently handle definite articles of the singular only.
	 * There is a full set of test cases at:
	 * http://translatewiki.net/wiki/Portal:Ksh#GRAMMAR_Pr%C3%B6%C3%B6fe
	 * Contents of the leftmost table column can be copied and pasted as
