IMHO, the default value of GRASS_PAGER ought to be $PAGER, if that is
set.

Some people might actually need the pager, so I wouldn't recommend
removeing the code. Those who don't want a pager can always use
GRASS_PAGER=cat (as I do).

We should change the name for 7.x. It isn't an "rc" file in the
conventional sense.

Note that ~/.grass.bashrc only affects the interactive shell which is
spawned from Init.sh; it doesn't affect the operation of Init.sh
itself. For that, use ~/.bashrc (or similar).

It might be worth having a separate rc file which is sourced from the
top of Init.sh. Also, on the subject of potential Init.sh changes, I'd
suggest getting rid of the $HOME "games" and just setting HISTFILE to
put the history file in the mapset directory (AFAICT, that is the
primary purpose of the $HOME stuff).
