Okay, I'm back home and ran tests.  The vast majority of my
implementations return #f to both (eq? (vector) (vector)) and
(eq? (string) (string)).  I also tested bytevectors in those
implementations that made it easy to do so.  Here are the cases that
returned #t:

Chez returned #t for both strings and vectors.

Icarus (but not Vicare) returned #t for vectors but not strings or
bytevectors.

Ypsilon returned #t for all three cases.

NexJ returned #t for vectors but not strings.
