diff.c: Output the text graph padding before each diff line

Browse Source 
Change output from diff with -p/--dirstat/--binary/--numstat/--stat/
--shortstat/--check/--summary options to align with graph paddings.

Thanks Jeff King <peff@peff.net> for reporting the '--summary' bug and
his initial patch.
