original commit log by miller@OpenBSD r1.46:
Fix exit value when diffing directories with missing files and the -N
or -P options are not used. From Ibrahim Khalifa
Fix exit status with -rq when there is a file in one directory but not another,2017-07-17T18:06:42ZEnji Cooperngie@FreeBSD.org2017-07-17T18:06:42Zurn:sha1:2d920b13cbf3fe93b5ed2c4aa4254d24c0fc95bb
i.e., when print_only is called.
Prior to this change, -rq was always returning 0. After this change it will
return 1 if there is a difference between two directories.
This fixes compatibility with GNU diff and unbreaks backwards compatibility
expectations.
Found when trying to extend diff_test:brief_format_test.
