,----[ http://www.faqs.org/rfcs/rfc2822.html ]-
| 2.1.1. Line Length Limits
| 
|    There are two limits that this standard places on the number of
|    characters in a line. Each line of characters MUST be no more than
|    998 characters, and SHOULD be no more than 78 characters, excluding
|    the CRLF.
| 
|    The 998 character limit is due to limitations in many implementations
|    which send, receive, or store Internet Message Format messages that
|    simply cannot handle more than 998 characters on a line. Receiving
|    implementations would do well to handle an arbitrarily large number
|    of characters in a line for robustness sake. However, there are so
|    many implementations which (in compliance with the transport
|    requirements of [RFC2821]) do not accept messages containing more
|    than 1000 character including the CR and LF per line, it is important
|    for implementations not to create such messages.
| 
|    The more conservative 78 character recommendation is to accommodate
|    the many implementations of user interfaces that display these
|    messages which may truncate, or disastrously wrap, the display of
|    more than 78 characters per line, in spite of the fact that such
|    implementations are non-conformant to the intent of this
|    specification (and that of [RFC2821] if they actually cause
|    information to be lost). Again, even though this limitation is put on
|    messages, it is encumbant upon implementations which display messages
|    to handle an arbitrarily large number of characters in a line
|    (certainly at least up to the 998 character limit) for the sake of
|    robustness.
