[bug-mailutils] Adding subject in msg-send.c

[Kidong Lee]

Hello, 

When I try to add Subject header in examples/msg-send.c(see diff file),
But there's no Subject header in the received mail.(The patch has no effect.)
On the contrary, When I comment out message_set_stream()(at 121 line,
version 0.3), there's Subject header in the mail.(In this case, there's
no body, of course)

There seems to be some kind of conflict between message_set_stream() and 
message_set_header().

Is it bug? or is there any fault?
