Of course, I should have suffixed that; Charles and I bickered about this
for other reasons at one point.

The problem with putting it into the cookie comes in when someone calls
funopen(), fropen(), or fwopen().  We'd need a flag bit somewhere in the
actual __sFILE that indicates "this cookie is a real stdio cookie, and not
user-supplied" so that we don't tromp on a FILE created by funopen().
