[FFmpeg-cvslog] options: stop after option is found.

[Clément Bœsch]

ffmpeg | branch: master | Clément Bœsch <clement.boesch at smartjog.com> | Wed May 30 14:40:28 2012 +0200| [e00b2d284e492e4f40dcf41392518b7a7d652901] | committer: Clément Bœsch

options: stop after option is found.

This reverts 78da04384a6c22820518706d84631006d31a85ea; it is not
required anymore since the previous commit (these extended checks were
for the -timecode option in both muxers and encoders), and reduces the
diff with the fork.
