Multi word commmands / subcommands without quoting.

[cafce25]

Is your feature request related to a problem? Please describe.

In recent years it's become more and more common to split the usages of a program into multiple sub commands, i.e. cargo has cargo run, cargo build, ... each with their own, specific help. But halp doesn't support multi word commands without quoting.

Describe the solution you'd like

It would be great if one could just do halp cargo build and get help for the build subcommand.

Describe alternatives you've considered

It's currently possible to get that help by simply quoting the command halp "cargo build", therefore it might not be worth the effort to support multiple words further than escaping.

It seems like a reasonable feature, but I took a fast look at the current implementation for the CLI arguments parsing and I can't find an inexpensive way to implement this feature
