Like others, this seems potentially useful even if I probably wouldn't
use it myself. Another more complicated way to think of it would be to
give a list of domains to omit (so if 90% of the committers are
@redhat.com, we can skip that, but the one-off contributor from another
domain gets their fully qualified name.
But that's a lot more complicated. I don't mind doing the easy thing
now, and even if we later grew the more complicated thing, I wouldn't be
sad to still have this easy one as an option.

What happens if the email doesn't have an "@"? I think you'd either end
up printing a bunch of extra cruft (because you're not limiting the
search for "@" to the boundaries from split_ident_line) or you'd
crash (if there's no "@" at all, and you'd get a huge maillen).
There's also no need to use the slower strstr() when looking for a
single character. So perhaps:
const char *at = memchr(mail, '@', maillen);
if (at)
maillen = at - mail;
strbuf_add(sb, mail, maillen);

As others noted, this could cover %aU, too (which is broken; you need to
handle 'U' alongside 'E' and 'N' earlier in format_person_part()).

Maybe:
git log --pretty="%an %ae %au"
or
git log --pretty="%an%n%ae%n%au"
which is shorter and runs more efficiently?

These values come from our hard-coded test setup, so it would be more
readable to just expect those:
{
echo "$GIT_AUTHOR_NAME" &&
echo "$GIT_AUTHOR_EMAIL" &&
echo "$GIT_AUTHOR_EMAIL" | sed "s/@.*//"
} >expect
For the last one, also I wouldn't be upset to see test-lib.sh do
something like:
TEST_AUTHOR_USERNAME=author
TEST_AUTHOR_DOMAIN=example.com
GIT_AUTHOR_NAME=$TEST_AUTHOR_USERNAME@$TEST_AUTHOR_DOMAIN
to let tests like this pick out the individual values if they want.
