Any specified X: (exclude) pattern matches are _not_ ignored. Used with "--nogit", directory is used as a pattern match, no individual file within the directory or subdirectory is matched. Used with "--git-blame", does not iterate all files in directory Using "--git-blame" is slow and may add old committers and authors that are no longer active maintainers to the output. Using "--roles" or "--rolestats" with git send-email --cc-cmd or any other automated tools that expect only ["name"] <email address> may not work because of additional output after <email address>. Using "--rolestats" and "--git-blame" shows the #/total=% commits, not the percentage of the entire file authored. # of commits is not a good measure of amount of code authored. 1 major commit may contain a thousand lines, 5 trivial commits may modify a single line.
