[FFmpeg-user] lying about metadata output?

The input metadata is copied to the output file 
in ffmpeg (the application). The application 
cannot know if the muxer will be able to write 
the metadata or not (it may only support some 
specific tags) or if it will just write some 
metadata independently of what was requested to 
make sure valid files are written (as in this 
case).
There may be a bug but I believe the output 
metadata print should just be interpreted as 
what it "tries" to mux.
