In the spirit of this, a lot of (rather tedious) work needs to be done on the 
error messages themselves to enable color syntax highlighting. Specifically, 
replacing ' ' with ` `, and adding ` ` around %s formats when code is being 
emitted to the %s.

It's tedious because of all the messages in test/fail_compilation/* that need 
updating.

It would also be helpful to pull things like:
