Although as Dscho mentions, it's particularly irritating because it is
not part of the paginated output.

Let's bite the bullet and jump straight to --use-mailmap in case (4).

While at it, add a new log.mailmap setting "auto" that can be used to
explicitly request the new automatic behavior (so that e.g. if
log.mailmap is set to "true" system-side, I can set it to "auto" in my
per-user configuration).
While I think "revert to hardcoded default" may be a good idea, I do
not think the hardcoded default you implemented that changes the
behaviour based on the output destination makes much sense.  If I
want to eradicate junkio@cox.net from my paged/interactive output, I
want to eradicate it also in the output piped to the script I use
for authorship stats.  

I suspect that you may have misread the "is interactive" bit in the
original; that was used only to decide if we are going to warn.

Anyway, how about this much simplified version?

Subject: [PATCH] log: flip the --mailmap default unconditionally

It turns out that being cautious to warn against upcoming default
change was an unpopular behaviour, and such a care can easily be
defeated by distro packagers to render it ineffective anyway.

Just flip the default, with only a mention in the release notes.
