It does accept $PAGER as a definition of what tool to use for the
purpose, though that wasn't documented in the apropos(1) man page. I
just added it.

Due to evidently historical reasons (as I understand it), interestingly
the man(1) code handles this rather differently than apropos(1) does,
with more considerations (about checking and sanitizing input), and a
different call to run the pager.
