Since the functions expect string values, they should default to empty strings. And since an array with one empty value is returned when splitting a string with a delimiter, we should make sure make sure there's a value before splitting.
As it's currently written, you can't use the extension until you manually populate the textareas via the Options page, because a JS error happens if you use the buttons.
To test repeatedly I had to call chrome.storage.sync.clear() between tests to clear out values.
