Hmph, the way I read revision.c::commit_match() is that we check
with "--grep=bar --author=Ævar" and then emit the commit if that
check fails when --invert-grep is in effect (instead of emitting the
commit when the check succeeds, which is the normal case).

So there is one commit that didn't pass "has 'bar' and written by
Ævar" check that was written by you in the recent past (iow,
recently you were writing bar all over the place).  Changes by other
people by definition does not pass "has 'bar' and written by Ævar"
check, on the other hand.
