I tend not to use aliases, or I get too used to them and use
them on other systems and unexpected things happen :) So 
it wasn't defined there, no; and I'd checked out /etc/bashrc
and /etc/profile et cetera pretty heavily a while ago whilst
trying to locate this LESSCHARSET thing, and discovering it
wasn't in those, either...

I didn't know about the options $MANOPT, $PAGER, and the
rest. But I re-read man man (ahem) and spotted references
to /etc/man.config. Duh. I should have done that in the
first place :) 

It sets all those and some more, and is heavily commented,
and includes
	PAGER		/usr/bin/less -is
And apparently -i is --ignore-case; and -s is --squeeze-blank-lines
(there's some really inventive long-options in here), which I 
didn't know before. (I don't tend to use less.)

I don't seem to have that one.

Heh. As I said, I don't tend to use them; and now I'm glad!

Thanks. It did.
