ProjectSettings.asset modified by NewLines whenever I do a fresh check out and open the project

I've got a similar problem to the one reported here

http://answers.unity3d.com/questions/293761/unity-35-svn-and-projectsettingsasset.html?page=1&pageSize=5&sort=votes

When I check out my git files & open the project with Unity the ProjectSettings.asset file is modified. Git reports that there are NewLines. i.e.

The text is identical, but the files do not match! The following differences were found: Newlines

I've spent time fixing other issues where files are modified once the project is opened. This is the last one. How can I resolve it?

Notes:

• I already had Asset Serialization set to "Force Text"

• My project is loading with errors & warnings that are next on my todo list but don't prevent me from running the scene
