	RFC822 does not say "nonblank":
True. RFC822 allows a local-part to be a quoted-string
which can explicitly include white space (pages 27, 11
and 10).
However, your quote from pp 30/31 implicitly says you
have to be VERY careful with such things:

	      6.2.4.  DOMAIN-DEPENDENT LOCAL STRING

	         The local-part of an  addr-spec  in  a  mailbox  specification
	         (i.e.,  the  host's  name for the mailbox) is understood to be
	         whatever the receiving mail protocol server allows.  For exam-
	         ple,  some systems do not understand mailbox references of the
	         form "P. D. Q. Bach", but others do.
The example on pp 30/31 focusses on de period, but
how many mailers in use today on (e.g.) Unix systems
will accept "John Doe"@domain", but will fail on
"John   Doe"@domain?
