-h topic Response

[Noitarud]

Hello all,

In the help it says:

Getting help:
    -h      -- print basic options
    -h long -- print more options
    -h full -- print all options (including all format and codec specific options, very long)
    -h type=name -- print all options for the named decoder/encoder/demuxer/muxer/filter/bsf/protocol
    See man ffmpeg for detailed description of the options.

Print help / information / capabilities:
-L                  show license
-h topic            show help
-? topic            show help
-help topic         show help
--help topic        show help
-version            show version

I began using ffmpeg with an older version and had expected "-h topic" to list topics I could begin to get help on, and there is where you could have placed the -h filter=name and amoung the entries you could offer an option to list terms which would allow to query the definition and usage of "command support/slice threading/timeline support" amoung others.

So, if theres no point to "topic" can it be removed since it responds the same as just -h, or is it being backward compatible?
