We couldn't do that as-is, as 'grep -A 1' is equivalent to 'grep -A1' 
and people rely on that.

'grep -A 99999999999999999999999999999999999999999' does what you want 
already, even if 99999999999999999999999999999999999999999 is too big to 
fit into a machine word. Is that good enough? It would save your having 
to wait for the next grep release....

Alternatively, I suppose we could add syntax like 'grep -A Inf' to do 
what's requested, where "Inf" is short for infinity.
