Title

PTF2057 - Fix for popper daemon to sned the body of the last
message

Product And Version
--------------------

UnixWare 2.01  UnixWare 2.02

General Description.
-------------------

To read the body, the code was looking for the offset of the next 
message in the file. For the last message as there are no messages 
after that the offset of next mesdsage was not set and so it was zero. 
It was not reading the body at all to send to the client. The condition 
is changed to take care of this flaw by checking  for the end of the 
message as the offset of the message and length of the message.
