diff --check: minor fixups
There is no reason --exit-code and --check-diff must be mutually
exclusive, so assign different bits to different results and allow them
to be returned from the command. Introduce diff_result_code() to factor
out the common code to decide final status code based on diffopt
settings and use it everywhere.
Update tests to match the above fix.
Turning pager off when "diff --check" is used is a regression.
