As said on IRC, I would prefer something like:

 ./ffmpeg -help filters
 ./ffmpeg -help filter=curves

Same with all the tools, supporting codecs, formats, etc.

And as a default message for -h and -help, an extended version of the "Getting
help" from ffmpeg.c, and without any option displayed unless you explicit
"full" or some module.
