(I can't work out whether this is a bug report or an enhancement request. Perhaps it's both!)

youtube-dl -F (youtube-dl --list-formats) output is often wider than 80 characters. For example (hard wrapping the output at column 80):

$ youtube-dl -F upyrWwstEMY

Also, to confirm the maximum line length of the output:

$ youtube-dl -F upyrWwstEMY | awk '{if(length>max)max=length}END{print max}'
104

Could you please either provide an alternative output format for -F/--list-format which is constrained to a maximum of 80 characters wide, or change the default output format to be constrained to 80 characters.

Thank you!

You can build whatever output you need based on --dump-json.
