So in RFC2822 an item-value can be an atom, which
covers the cases given elsewhere by Bill McQuillan
in this thread
No need to remove it, as it is already consistent
Maybe not exactly, 2821bis-01 says:
| String = Atom / Quoted-string
With <Quoted-String> you get <qcontent>, that again
can contain <qtext> (e.g. raw unescaped NO-WS-CTLs)
or <quoted-pair>s '\\' and '\"' plus other redundant
<quoted-pair>s (i.e. unnecessary backslashes).
"String" should be retained for consistency with
RFC2822 and compatibility with current usage.
Maybe replacing <String> by <Atom> is acceptable (?)
