MFC r242514:
	Revert the change that makes less default.

	Since I've committed this I've receieved roughly an equal
	amount of email thanking me for making this change
	and asking me to revert it.

	I've resisted making this change because
	new users tend to prefer less over more
	and these users are the least likely to know
	how to change the PAGER on their own.
