Using "--git-blame" is slow and may add old committers and authors
that are no longer active maintainers to the output.

+ 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.

+ --git,
+ --git-min-signatures, --git-max-maintainers, --git-min-percent, and
+ --git-blame
