question size of explanatory responses

[Todd Olson]

Hi

Along with Numeric codes, nnrpd returns explanatory responses to news clients.
RFC 977 describes the text as being CR-LF terminated strings with the
last string being '.'  However nothing appears to be said about
   a) a length of the strings
   b) a limit on the number of strings
Are there any specified length constraints on these text strings?
Are there any common limits in INN?
Are there any common limits in news clients that people have encountered?
