         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 TShark 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

         intended to be transmitted to or from the host environment as a
         block when a new-line character is encountered".

         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 TShark 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. */
