Grep has general RRI problems. I think the grep team needs to decide if

No kidding it has problems! It seems like almost everywhere I look
there's a bug waiting to happen. For example thanks to you I found this
bug with grep 2.18:
LC_ALL=C grep '/[a-[.e.]]/'
grep: Invalid range end
Which is bogus, as 'e' is a perfectly valid range end. But at least
this is an improvement over grep 2.16 and 2.17, which both dumped core
on this example!
I prefer RRI myself, and would like to see GNU grep move in that
direction. Not sure how to get there, though.
