Hi all,

"man" needs PAGER env var to override a default pager. And if i remember
correctly, some programs want this var too. So I just used this env var
to use user's pager in GRASS.

I remember that there was inconsistency between grass modules which need pager.
So I decided to check this env var, which may be already set or not.
Using this var, we can use the same pager system widely.

If this causes any problem, PAGER may be renamed to GRASS_PAGER or etc.
Then, non-$PAGER user won't experience any inconsistency between GRASS and
UNIX.


Just my thought.
