I'm not sure if this should be tagged as "forwarded" because the upstream bug is independent.
https://savannah.gnu.org/bugs/index.php?33080 This is currently in "Needs info" limbo. I see a lot of consensus on the broader net that combining -c and -o would be useful for counting occurrences instead of matching lines (and indeed, it's hard to see how any other semantics could be both well-defined and useful). /* era */ -- If this were a real .signature, it would suck less. Well, maybe not.
