Option to ignore subtitles

[Alex]

Steps that will reproduce the problem?

1. ffmpeg -i file.mkv -map 0 -sn ./file.m4v

What is the expected result?
To have no subtitles in the output

What happens instead?
In this case an error (see below)

Possible workaround:
ffmpeg -i file.mkv -map 0:0 -map 0:1 ./file.m4v

Any additional information:

$ /usr/local/bin/ffmpeg -y -i test.mkv -vcodec copy -map 0 -sn test.m4v

Also "-map 0 -scodec copy", "-map 0 -scodec xsub", or "-map 0 -scodec dvdsub" doesn't work with this file. But this might be an issue for another ticket. Actually, I just want to convert all my files w/o subtitles but with all audio tracks automatically.

The correct syntax is now "-map 0 -map -0:s", but I would also prefer if "-map 0 -sn" would work...
