Repro steps:

1. Create a new project
2. Create a new "Shader" -> "Standart Surface Shader"
3. Open the new Shader file and show the line endings
4. Paste in the provided Shader code and convert the line endings to Windows (CR LF)
5. Save the Shader file and enter the Unity Editor
6. Notice the "inconsistent line endings" error
7. Enter back to the Shader file and notice that it needs to be reloaded
8. Reload the Shader file and notice that at the Top of the file a new line was automatically added that has different line ending from the rest of the code

Expected result: The automatically added line endings should be like the rest (CR LF in this case)
Actual result: The automatically added line endings are different (LF) than the rest (CR LF)
