Re: git grep -P is multiline for negative lookahead/behind

Is this expected behavior, and if so, why/where is this documented?

I do not think "git grep" was designed to do multi-line anything,
with or without lookahead.  If you imagine that the implementation
attempts its matches line-by-line, does that explain the observed
symptom?
