This was done by first checking all files in the repository root by hand, and
then by doing the following:
$ npm i get-stdin@4
$ cat clean.coffee
fs = require 'fs'
stdin = require 'get-stdin'
stdin (text) ->
for file in text.trim().split('\n')
contents = fs.readFileSync file
.toString().replace /\s*$/, '\n'
fs.writeFileSync file, contents
return
$ ls !(node_modules)/**/*.coffee | coffee clean.coffee
