It sounds like we already have the first one, that the second one might be
preferable, and that the third one is going to be hard to implement and
even harder to document clearly.

I suggest that we first find out what POSIX says about shells in this
regard (Zoltan?  Are you out there?), and then choose whichever of the
first two gets us closest to that.

Then we worry about how to get all the way to POSIX (if we aren't) *after*
the next major release (3.2 or whatever it will be, not the next 3.1.x).
