That is a dark corner in the spec.  RFC 2617 specifies unq(X)
as "the value of the quoted-string X without the surrounding
quotes".  RFC 2831 adopted this algorithm in its <qdstr-val>.

I-D 2831bis was about to change it, but the SASL folks later
decided to give up on updating RFC 2831 as hopeless case - an
unfixed erratum in RFC 2617 rendered "md5-sess" in RFC 2831
and RFC 2617 as incompatible, among other Digest-MD5 issues.  

Whatever you do - please be very clear about it, add MUSTard,
a note in the 2616bis security considerations, and recommend
"future work" for a 2617bis based on 2616bis.
