I'd like to see these specs structured as follows:

```coffee
describe "when 'whitespace.ignoreWhitespaceOnCurrentLine' is true", ->
  it "removes the whitespace from all lines, excluding the current line", ->
    
describe "when 'whitespace.ignoreWhitespaceOnCurrentLine' is false", ->
  it "removes the whitespace from all lines, including the current line", ->
```

I'm not convinced we need a separate test for lines that are only whitespace vs lines that have trailing whitespace. Thoughts?
