I may be misunderstanding the question, but I personally would feel
that "git grep --not <ANYTHING>" is OK to say "the entire line is at
fault that it did not satisify the criteria to match <ANYTHING>".
I.e., I'd be happy if --column marked the first column as the
beginning of the match, or --color painted the entire line in the
output of the former.
