The description changed in grep 2.22, to match the 2.22 (also, 
2.6-and-earlier) behavior.

As you say, the 2.22 behavior does not seem ideal. However, the 2.7 
through 2.21 behavior wasn't ideal either. It's not clear which behavior 
is better overall, nor is it clear whether we could unify parts of the 
two behaviors to get the best of both worlds. I'd rather not add yet 
another option in this area, if that can be avoided.
