reverse grep

[lejeczek]

hello

I realize that
-v -B1 -A1 pattern
does not do what I presume many of us regular users assumed
but! how nice would such a function be if included?
to reverse a patter plus surrounding lines
very very! nice
please please consider in future releases

a do apologize if the address I send this message to is not 
for the purposes like feature requests, I ain't a subscriber 
of the list
many! thanks
