How do I explicitly print out a subcommand's help text (usage)?

craftyguy commented 2 years ago

this works for me:

$ foo bar -h

where bar is the subcommand

Currently you can show help on a flaggy.Parser, but not a flaggy.Subcommand. I agree that it would be nice to call help on a flaggy.Subcommand directly, but it would take a little re-factoring to prevent duplicate code... Right now this is done via a template rendering that happens on the Parser...
