[net.unix-wizards] long messages are silently truncated

jes (07/22/82)

This is a problem with mail.c on PDP-11's.  I found it on USG
4.0, but I suspect it may be found elsewhere.

In function copylet(), the variable k is initialized to the size
of the message.  If a message is longer than 2^15 bytes, bad
things will happen.  The solution is to change the declaration
of k from int to long.
