This lets you say: git grep --all-match -e A -e B -e C to find lines that match A or B or C but limit the matches from the files that have all of A, B and C. This is different from git grep -e A --and -e B --and -e C in that the latter looks for a single line that has all of these at the same time. Signed-off-by: Junio C Hamano <junkio@cox.net>
