This allows overriding the build-time PAGER_ENV variable

Inspired by part 1 of an idea from Kyle J. McKay at:

This commit message is missing the "why" (I tried to get it from the
referenced email, but I am still confused).

What does this buy you over:

  GIT_PAGER='less -whatever-options-you-like'

? Sure, you have to say "less" there and not just "if we happen to be
using less, use these options with it". But that distinction is
important for a build-time default, not for a run-time one. And by
pointing people to GIT_PAGER, they can do a lot _more_ than they can
with PAGER_ENV, including the full power of the shell (brian gave an
example of "par | less" earlier; I use "diff-highlight | less").
