Linting Vim files

If you add or change a Vim file, the CI will use vint to ensure best practices. Therefore it's recommended idea to run it locally first, before creating a pull request.

Install vint.
Recursively lint all Vim files:
```
$ vint .
```

Writing test files

Generating test files

Use the generator to create Vader files from their canonical test data:

" in Vim
:source lib/generate.vim
:Generate word-count

This would fetch the canonical test data, decode the JSON to Vim data types, iterate over the result, and put the tests in a new unnamed buffer.

This script requires Vim 7.4.1304+ for json_decode(). It also relies on the netrw plugin (:h netrw), but that one is shipped and sourced by default.

Type mismatch exceptions

Older Vims don't like changing types for the same variable. If your tests use global variables, unlet! them in a Before block at the top of the Vader file.

When each test uses let expected = ..., then put this at the top:

Before:
  unlet! expected

This is patched as of Vim 7.4.1546, but we shouldn't assume versions in favor of compatibility.
