Here, the documentation seems to promote --mailmap over --use-mailmap.

So, along the lines of patch 2/3, I wonder if this should instead make
--mailmap the "real" option and --use-mailmap the alias; namely, use
OPT_ALIAS for --use-mailmap and place it after --mailmap. (Genuine but
very minor question; should not hold up acceptance of patch.)
