regex: match current GNU grep behavior These symbols have not matched GNU grep behavior for quite some time. Fix prompted by Balazs Kezes bug report at: http://bugs.gnu.org/20974 * lib/regex.h (RE_SYNTAX_GREP, RE_SYNTAX_EGREP): Change to match current GNU behavior. Simplify by expressing it as differences from POSIX BREs and EREs. (RE_SYNTAX_POSIX_EGREP): No longer differs from GNU behavior.
