In fairness to ffmpeg, its manpage's not-tiny "EXAMPLES" section /does/
include a command that uses "-c copy" with the correct syntax also
provided by Vangelis. They do try, they may just not always have a howto
that fits exactly what you want so you have to look through a few. I've
similarly found helpful the "EXAMPLES" section from manpages for related
tools like mplayer.
