The Visual C++ 6.0 C implementation doesn't do what is intended;
even if you set a stream to be line-buffered, it still doesn't
flush the buffer at the end of every line.
So, if the "-l" flag was specified, we flush the standard output
at the end of a packet. This will do the right thing if we're
printing packet summary lines, and, as we print the entire protocol
tree for a single packet without waiting for anything to happen,
it should be as good as line-buffered mode if we're printing
protocol trees. (The whole reason for the "-l" flag in either
tcpdump or Rawshark is to allow the output of a live capture to
be piped to a program or script and to have that script see the
information for the packet as soon as it's printed, rather than
having to wait until a standard I/O buffer fills up. */
