It's the encoded length, though of course "> " would encode
without change.  This is all I could find in a quick grep of the
RFCs, in Appendix B of RFC 1521:

   The following guidelines may be useful to anyone devising a data
   format (Content-Type) that will survive the widest range of
   networking technologies and known broken MTAs unscathed.

   [...]

   (4) Lines longer than 76 characters may be wrapped or
       truncated in some environments.
