Thank you Bagas for adding the documentation. I think the only that disturbed Junio is the use of the word "metadata",
which is used internally, but not in the official documentation aimed at the git user.

Starting from your patch, I added some suggestions for alternative wordings.

Regards,
Matthias

    blame: document --color-* options

    Commit cdc2d5f11f1a (builtin/blame: dim uninteresting metadata lines,
    2018-04-23) and 25d5f52901f0 (builtin/blame: highlight recently changed
    lines, 2018-04-23) introduce --color-lines and --color-by-age options to
    git blame, respectively. While both options are mentioned in usage help,
    they aren't documented in git-blame(1). Document them.
