[PATCH] Don't use the pager when running "git diff --check"

In 89d07f75 "git diff" learnt to not run the pager if the user passes
the --exit-code switch. This commit does the same for the --check
switch for the same reason: we want the user to get the exit status
from "git diff", not the pager.

This really should have been part of my original patch,
([PATCH 1/5] "diff --check" should affect exit status"), but I only
just discovered this now.
