Tracked down the syntax highlighting config file for KDE's Kate Editor to colorize Prolog code

This is rather intimidating. It’s not parsing Prolog, just looking for recognizable blocks of syntax. Dayum!

This made me laugh:

	<!-- These are in fact bogus, DO NOT USE them and bug the ISO standard
	commitee to abandon char_conversion/2 and to apply common sense to the
	semantics of include/1 and ensure_loaded/1, i.e. to handle recursion.
	Bomb them w/ e-mails! It's not the purpose of a standard to fixate
	errors till eternity. -->
