​Being able to use "\pset pager"​

​to toggle the capability seems useful.

Thus I'd suggest establishing a new "pager_minlines"​ option that if unset
(default) maintains the current behavior but which can have a value (0 to
int_max) where 0 ends up basically doing the same thing as "always" mode
for "pager". Leaving the value blank will cause the option to be unset
again and revert to the current behavior.
