This fixes up a couple of minor issues with the real built-in diff to be more usable: - Omit ---/+++ header unless we emit diff output; - Detect and punt binary diff like GNU does; - Honor GIT_DIFF_OPTS minimally (only -u<number> and --unified=<number> are currently supported); - Omit line count of 1 from "@@ -l,k +m,n @@" hunk header (i.e. when k == 1 or n == 1) - Adjust testsuite for the lack of -p support.
