I think this should be defined in the BNF as it is throughout RFC2251 (throught the use of the whsp definition).  It seems like much of sections 2.4 and 4  could be expressed in the BNF.

I agree, 2.4 should include these two restrictions.

If whitespace only includes space characters, do these problems go away?
