I also read it the same way Arvel did. Also, if it isn't interpreted
that way, you get ambiguities when multiple instances of a particular
header are listed and only some of the values are presented in z=. In
particular, the z= field is also supposed to help you work around header
reordering; you need all values to be there in order to do that.

The z= tag allows you to put as many or as few headers in it as you

so it might make sense to be more explicit.
Mike, it could just be me being dense. FWIW though this text was
understood by two of us here as meaning copy all the headers:
"A vertical-bar-separated list of header field names and copies of
header field values that identify the header fields present when the
message was signed."
Perhaps:
"A vertical-bar-separated list of select header field names and copies
of header field values that identify the header fields present when the
message was signed. It is not required to include all header field
names and values."
