In ~/.mailmap I see a line

Han-Wen Nienhuys and Jan Nieuwenhuizen <fred> # see note below

but in my repository no commits authored by fred, so this suggests to me
someone rewriting the history of the repository at some point of time in
order to get rid of nonsensical author attributions.

Maybe something can be found in the developer list archive?
