mbdemux demultiplexes mbox stream, invoking a command passed via arguments
for each of the contained 822 messages. That is, the 'From ' line and
empty line delimiting the message are not passed further along.
No decoding is being carried out on the messages. From-demunging is to
be done in the message handling program.
