Re: Update to RFC 5322 to allow "group" syntax in the "from" header

Executive summary: I sent myself some messages with an empty group in 
From: headers to see what various MUAs did with them.  Nothing broke.

* Alpine (my normal client)

Displayed OK.  Invented a matching Reply-To: line.  If I reply, the To: 
line is empty.

* Thunderbird

Displayed OK. Reply put the same empty From: group on the To: line, 
rejects attempts to send it with a message saying to fix the To: line.

* Evolution

Displayed OK. Reply has a blank To: line.

* Android mail

Displayed OK. Reply has a blank To: line.

* Squirrelmail (popular webmail IMAP client)

Displayed OK, reply put the null group on the To: line and let you try
to send mail to it.

* Yahoo Mail

Filed as spam but displayed reasonably.  Reply had an empty To: line.

* Gmail

Filed as spam but displayed reasonably.  Reply had an empty To: line.

* Hotmail aka outlook.com

Displayed OK. Reply put the same empty From: group on the To: line, 
rejects attempts to send it with a message saying to fix the To: line.
