Subject: spec: clarify that []byte("") must be non-nil
X-Git-Tag: go1.22rc1~1168

spec: clarify that []byte("") must be non-nil

The example text below suggests that []byte("") always evaluates to
the non-nil value []byte{}, but the text proper doesn't explicitly
require that. This CL makes it clear that it must not evaluate to
[]byte(nil), which otherwise was allowed by the wording.
