getopt-gnu: match recent glibc fixes and posix ruling The POSIX folks admitted that codifying the behavior of GNU getopt on a leading '+' in optstring is worthwhile, for writing programs such as env(1) even when POSIXLY_CORRECT is not defined. http://austingroupbugs.net/view.php?id=191 However, the ruling is an enhancement request for the next version of POSIX, and is not binding on platforms that comply with POSIX 2008, so it should only be enforced for getopt-gnu. * tests/test-getopt.h (test_getopt): Strengthen tests of leading '+' handling, when requesting extensions. * tests/test-getopt_long.h (test_getopt_long): Strengthen test of 'W;' handling. * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Detect glibc 2.11 bug. * doc/posix-functions/getopt.texi (getopt): Document this. * doc/glibc-functions/getopt_long.texi (getopt_long): Likewise. * doc/glibc-functions/getopt_long_only.texi (getopt_long_only): Likewise.
