Y'all might want to consider basing RE_SYNTAX_POSIX_EGREP off of RE_SYNTAX_POSIX_EXTENDED; that would have gotten this case.
At some point we should clean out those old RE_SYNTAX_* macros; half of them are just plain wrong anyway. However, doing that will require a fix to glibc, which would take quite a long time to propagate through, and in the meantime the attached patch should suffice. I've installed it and it should appear in the next grep release. Thanks for reporting the bug, Nathan.
