ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Fri Feb 22 23:01:54 2013 +0100| [358628074c314c8ec6d433a740e9176e7aefa124] | committer: Anton Khirnov

print_options: do not generate docs for options without enc or dec flags

Those are not usable from the avtools, so mentioning them in the
manpages just confuses the reader.
