* Escape all paths for ssh file changes using `vim.fn.shellescape()`
* Change away from `vim.fn.shellescape` to custom implementation
Really, only escape `'` with `'\\''` so that it will:
- exit the single quote mode
- escape out a single quote character
- and get back into the single quote mode
Also format long line so linter doesn't complain
* Adding doc comments to the shellescape function
* Adding actual words to the doc comment
