send-email: accept long lines with suitable transfer encoding

Browse Source 
With --validate (which is the default), we warn about lines exceeding
998 characters due to the limits specified in RFC 5322.  However, if
we're using a suitable transfer encoding (quoted-printable or base64),
we're guaranteed not to have lines exceeding 76 characters, so there's
no need to fail in this case.  The auto transfer encoding handles this
specific case, so accept it as well.
