are multiple simultaneous signatures acceptable Open PGP behavior
?

The first example you gave was of a nested one-pass signature, and
the
second example was a clearsigned message with two signatures after
it.

While it is unfortunate that 6.5.8 can't handle them, both of these
constructions are legal in OpenPGP (as per sections 5.4 and 7).

6.5.8 can handle all except the clearsigned messages
(btw, 7.xx acts like 8, and handles everything)

is there a gnupg command syntax that would allow for a nested one
pass signature during clearsigning ?

There is no such concept.  All clear signatures by their nature (being
a signature that can be processed in one pass, by specifying the hash
before the data begins) are one pass.
