Help for cardinality-specified values #12

Closed mattgodbolt closed 5 years ago

mattgodbolt commented 5 years ago

It would be great if the cardinality was represented in some way in the help. Currently if I specify a cardinality of (1, 1000) (see #11), the help text is still: test <input...> (I specify "input..." as the name for now as a workaround.

Ideally this would be something like the GNU help system's: test: <input> [<input>...] to show there's 1 or more parameters (although because of #11 we can't say "any number" currently)
