`ember g route my-route` always turns the router.js file into `crlf` mode

Output from ember version --verbose && npm --version && yarn --version:

I am able to recreate the bug from the following:

0.) open Git Bash

1.) Ember new testbug

2.) cd testbug/app

3.) check the newline character type (should all be set to UNIX)

find . -not \( -path './.git' -prune \) -type f -print0 | xargs -0 dos2unix -ih

The router.js file has mysteriously converted into CRLF format.

I have also noticed this same thing occurs when performing ember d route my-route

[rwjblue]

ember-cli does not control the generation (or insertion) of this file. The route blueprint in ember-source (here calls in to ember-router-generator to get the updated code to write (see here). I think maybe we need to add another option to recast.print for it to autodetect the right line endings to use? Not sure exactly what needs to be done to fix that but I think the issue should be moved over into ember-router-generator's repo.
