bug#34438: [8.30, info] doc error in -R

[Filipp Gunbin]

Hi,

There's a small bug in doc here:

‘-R’
‘--rfc-email’
...
     This format conforms to Internet RFCs 5322
     (https://tools.ietf.org/search/rfc5322), 822
                                              ^                               
     (https://tools.ietf.org/search/rfc2822) and 822
...

Should be 2822, obviously.

Thanks.
