Fix produced text address list string according to rfc 2822

A.1.2. Different types of mailboxes

This message includes multiple addresses in the destination fields
and also uses several different forms of addresses.

From: "Joe Q. Public" john.q.public@example.com
To: Mary Smith mary@x.test, jdoe@example.org, Who? one@y.test
Cc: boss@nil.test, "Giant; "Big" Box" sysservices@example.net

Hi everyone.

Note that the display names for Joe Q. Public and Giant; "Big" Box
needed to be enclosed in double-quotes because the former contains
the period and the latter contains both semicolon and double-quote
characters (the double-quote characters appearing as quoted-pair
construct). Conversely, the display name for Who? could appear
without them because the question mark is legal in an atom. Notice
also that jdoe@example.org and boss@nil.test have no display names
associated with them at all, and jdoe@example.org uses the simpler
address form without the angle brackets.

Another try to fix text string generation :-)

It is not required for any email address, only for certain cases, if you agree - I can make better code that will add quotes only if they are needed.
