	I don’t seem to understand; is mark-active ever supposed to
	become nil when /not/ in the transient-mark-mode?

	Personally, I find the latter distracting enough not to ever
	turn it on.  So, I guess that the above would mean that I’d
	always be getting anything I have for the region (which may
	easily be a substantial portion of the buffer) for the default.

	Thus, at the very least, the above should probably use
	(and transient-mark-mode mark-active) as the condition, or
	something like that.
