   A very small patch to "mn" of a month or two ago is included below.
The README in the shar gives details (what few there are on a 5-line
patch =8) ). Thanks.

X   This is a trivial change; mn wasn't handling messages without a
X"Subject: " header line correctly. Thanks to Kingsley Kerce and
XHenry Bruce (who I couldn't respond to by mail; sorry) for pointing
Xout the problem. 
X   As patched, mn substitutes the null string "" as the subject for
Xsubjectless messages. However, line 60,
X   static char *nullsub = "";
Xcan be changed to any string constant if desired.
