test-getopt: enhance test Add coverage of optind==0 for getopt_long, since coreutils depends on it. Also test an optstring containing "W;", since that tends to expose corner-case bugs (even in glibc, so the test is weaker than it could be). * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Require that getopt_long supports optind=0. * tests/test-getopt.c (OPTIND_MIN): Move... * tests/test-getopt.h (OPTIND_MIN): ...here. * tests/test-getopt_long.h (test_getopt_long): Add more coverage. Require that optind=0 works, since modern BSD supports it in addition to optreset, and since coreutils expects it. (test_getopt_long_only): New test. * doc/glibc-functions/getopt_long.texi (getopt_long): Document glibc shortcomings with 'W;', and enforcement of optind=0. * doc/glibc-functions/getopt_long_only.texi (getopt_long_only): Likewise.
