as I don't think you need the full path in $PAGER.

================
no, you don't need the full path. but at the moment i'm fine with either `most` or "whatever the default is". if i wind up with a list of preferences (or even a 2nd preference) i'll definitely use the loop idea.

	A student asked his old Sufi Master if he should tie up
	his camel for the night, so that it wouldn't wander
	away while they were sleeping or if doing so was an
	insult to God. Should he leave the camel untied to
	show his trust in God that the camel wouldn't run away?
	The Master replied "Trust God AND tie up your camel."
