docs: nit: subcommands

[lread]

It could be just my brain, but when I originally read about subcommands and saw :cmds in the dispatch table, it was not crystal clear to me that a string of commands invokes only one thing.

Are you OK with me making minor changes to the README to clarify? Maybe I'd define what a subcommand is. And mention that :cmds only results in the invocation of one thing.

[borkdude]

Yes please!

[borkdude]

Yeah a better name might have been :command-path or so?

[borkdude]

But docs will probably suffice

[lread]

Yeah, I was thinking maybe :command-chain?
But agreed, a docs-only change is sufficient.

I think my reason to call them this way was "those are the (sub)commands invoked from the command line". I kinda regret "cmds" instead of "commands" but I'd probably had regretted that for not choosing "subcommands", so I think we'll just have to live with this :)
