I am not sure I understand the utility here; using mailmap at log time
makes sense because these are old, established commits that may have
outdated contact information. But when writing patches with
format-patch, presumably these are still somewhat WIP patches. Is it not
better to just reset the author information before running
git-format-patch in this case?

If I've misunderstood the use case, please let me know.
