The quoting is for sticking outherwise invalid values into a range
restricted data stream.
In other words, it's useful for the 'F' in a leading "From" or the '.'
in a line starting with a '.' (to avoid invoking a byte stuffing state
machine on top of the quoting one that has to be there anyway) inside
a message body followin a DATA command in an RFC821 connection.
So it's not just GECOS data.
The problem with GECOS data is that if I have an ISP account that I
use to fan out mail for several users, and I use the address form:
To: Fred Smith <smith@isp.com>
and
To: Wilma Smith <smith@isp.com>
And fan out using the long name, I am using the GECOS data.
RFC822 specifies: "Each header field can be viewed as a single,
logical line of ASCII characters" ...
ASCII == 7 bits
Therefore the "To:" line GECOS ("long name") data must be 7 bit; 8 bit
data may be transfered, but if it is, it must be quoted.
