Ok -- but I'm still curious as to what other pager would be
preferable to less, more, or none?
Dave
Personally, I'm happy with less and none, but I very much prefer to
control it through $PAGER, because that's the common way to do it.
A more philosophical argument is that it's simply not ours to decide
what pagers users are allowed use. And we don't have to. $PAGER is
no less usable than the alternatives, yet provides all the choice
users could want.
