feat: Positional arguments

[agross]

Hi,

how would one create the Argu union for:

git push -f origin master git push origin master -f

The remote (origin) and branch (master) are positional arguments, i.e. the first and second non-option arguments on the command line.

Having two MainCommands (i.e. parameters without dashes) is not supported.

I don't believe this is possible, currently.

OK, I found we don't need it. Should I leave the issue open as a backlog item?

[eiriktsarpalis]

Sure, I can't think of a good way to encode positional arguments. Proposals/PRs are welcome.
