You're right that the regexp stuff is not really "dusty corners", but
none of those affect typical sed usage I think -- most sed usage being
really rather simple (and the old "regexps differ between traditional
unix tools" issue tends to dampen enthusiasm for really complex regexps
with those tools).

I looked over the various random uses of sed I have locally (a couple of
hundred instances), and the only thing which would potentially affect
any of them would be the SVR3 thing about no nested groups (does anybody
actually care about SVR3 though?!?).
