test: accept "==" as a synonym for "="
Make GNU coreutils' test recognize "==" as a synonym for "=". This is already the case in GNU coreutils' expr, bash, ksh, busybox ash, FreeBSD-current /bin/sh and /bin/test, and OpenBSD's /bin/sh. Before, env test a '==' a would fail with this diagnostic: "test: ==: binary operator expected". Now, it succeeds. * src/test.c: Accept "==" as a synonym for "=". * doc/coreutils.texi (String tests): Document it. Reported as http://debbugs.gnu.org/8263 Also see http://austingroupbugs.net/view.php?id=375
