I agree that is a better name (this was the exact thing I wondered about
with REG_STARTEND, but certainly what we _want_ is true "_buf"

I guess an argument that REG_STARTEND does what we want everywhere is
that the GNU implementation does what we want, and since it has been
around for over a decade presumably _somebody_ would have complained if
it did not match the NetBSD behavior.
