I am not interested in this patch very much myself, and after thinking
about it, I think my dislike largely comes from this syntax, and not from
the feature itself.  Any non-punctuation letter there looks like a sore
thumb.  Either "-L 20±5" or even "-L 20+/-5" would have looked a _lot_
saner.

Yes, radius sounds more sensible.  Another alternative would be to call it
"context", as in "grep -C <n>".
