Simple fix for #672. I'm slightly worried about the newline literal causing some weird pitfall with windows somehow.

Thanks for the suggestion here! Perhaps what we want is a denoImpl that just imports the tsImpl to make that assignment a little easier to grok. Do you want to take a swing at that? Otherwise, I can make the change myself when merging.
