I think this is the wrong course of action. Paul suggested updating the
doc to be more clear, not reverting the code.
If you use --with-included-regex, the patch is a no-op. Thus it can be
reverted.
Personally, I think grep should always use the included regex so that
then the behavior is consistent across all platforms everywhere; this
is why gawk always uses its own regex.
I wouldn't be surprised if GNU distros patch gawk's regex away to get
consistency with grep, sed, etc.
