So you're planning on converting POSIX regexen to PCRE so people don't need to worry about PCRE metacharacters that are POSIX literals? Seems tricky. (e.g. is "\w" a backslash and a w or a "word" character? what about search patterns of 10 instead of "10" they have different meanings in egrep(), you'll need to convert this, too.)
