allow suggestions for non-root commands

[deads2k]

Suggests were only appearing against the root command, but for nested command structures it makes sense to look for suggestions at the deepest command that was found.

@eparis Is there a corporate signature for red hat?

[deads2k]

Well clearly that had unintended consequences.

Good unit tests. I want to be able to use suggestions for nested commands, so that rootcommand subcommand misspelled-subsubcommand can get a suggestion. For that to work, I guess I'll need to annotate the Command somehow to indicate that it has no non-flag args.

@juanvallejo want to see what you can do? See the linked pull for usage.

Sounds related to the PR I just submitted in #284. I also factored out this findSuggestions() function which should make it easier to re-use. Maybe it should be public.
