"I prefer this address to be the one shown" is a good enough
justification for these entries ;-).

I suspect that another reason of retiring the two entries that may
not be captured in the log message is so that people does not have
to know the person is reachable both at microsoft and github.

It is somewhat sad that we need to carry these "via GitGitGadget"
entries in the file, but we are fortunate that the mailmap supports
the "differentiate two authors with the same e-mail with the human
readable name" feature so that we can label v2.25.0~3^2 and
v2.25.1~20^2~1 with the rigth authors.  If my counting is correct,
these two are the only ones that we mistakenly made GGG as the
author of a change.
