Ah, I see. I thought it was obvious.  I think users should be able to
easily know the standard error when they do t.tests.

People who do t-tests sometimes need to discuss their findings, and
the standard error may be an important consideration.  While one can
(of course) recover the standard error by doing some division, it is
inconvenient and, at least in the classroom, on the border of tedious.

We allow regression printouts with several layers of redundant information--

b  se t p

We should not make it difficult for users to discern the standard
error that is actually used in the t.test procedure?
