class Sprockets::SafetyColons

For JS developers who are colonfobic, concatenating JS files using the module pattern usually leads to syntax errors.

The ‘SafetyColons` processor will insert missing semicolons to the end of the file.

This behavior can be disabled with:

environment.unregister_postprocessor 'application/javascript', Sprockets::SafetyColons
