No, "here is a new bsd grep, but change all your scripts that have relied on legitimate behavior of grep in the past" is a non-starter. I haven't checked POSIX to see whether the particular construction I am using fits the spec or not, but I really don't care. We need to be feature-compatible with the GNU versions of these tools, both for legacy scripts and also for those users migrating over from linux.
