	/**
	 * The testIrcMsgForAction* tests are supposed to cover the hacky
	 * LogFormatter::getIRCActionText / bug 34508
	 *
	 * Third parties bots listen to those messages. They are clever enough
	 * to fetch the i18n messages from the wiki and then analyze the IRC feed
	 * to reverse engineer the $1, $2 messages.
	 * One thing bots can not detect is when MediaWiki change the meaning of
	 * a message like what happened when we deployed 1.19. $1 became the user
	 * performing the action which broke basically all bots around.
	 *
	 * Should cover the following log actions (which are most commonly used by bots):
	 * - block/block
	 * - block/unblock
	 * - block/reblock
	 * - delete/delete
	 * - delete/restore
	 * - newusers/create
	 * - newusers/create2
	 * - newusers/autocreate
	 * - move/move
	 * - move/move_redir
	 * - protect/protect
	 * - protect/modifyprotect
	 * - protect/unprotect
	 * - protect/move_prot
	 * - upload/upload
	 * - merge/merge
	 * - import/upload
	 * - import/interwiki
	 *
	 * As well as the following Auto Edit Summaries:
	 * - blank
	 * - replace
	 * - rollback
	 * - undo
