Patch for documentation?  Just replace ":" with "|"?

If I can write documentation, based on Moritz's comment, there seems to be backward compatibility right?

Does it mean the latest documentation can't be provided for ffmpeg?

Should I open new discussion about "-ac 2"?  Or continue with this thread?

Briefly, the source is DVD dumped with mplayer and ffmpeg down-mix audio with "-ac 2", but if didn't down-mix with ffmpeg, ffplay seems to need pan filter to playback.  Using "-ac 2" with ffplay dose not help.
