Fix always smart mode when enabling via commands

[andreyorst]

For some reason when %arg{1} is used in hooks it doe because it always empty for some reason when sent to function in a hook. I've changed that to a shell call to define hooks and now it works.

Merged.

Notes for the future:

I'd like to keep indentation more "regular" from now on - four spaces, not double-nesting, and indenting everything in brackets except for the module body. I'll do this later, since it'll help me understand how the code works now anyway.

I think we are past the point of needing a test harness for the Kakoune code. That's kind of a big undertaking, but I think I want that done before any more features. I'll look into that in a few days.

You can always tell me what you think should be rewritten or fixed, while pull request exists. I always welcome change requests.

@andreyorst Thanks, I will.

Apparently, I had added a few Kakoune tests, but they had bit rot. They are all fixed up and now running in CircleCI, along with Vim and Neovim tests.
