Why does testcase xml get saved in 1 line instead of proper xml format in multiple lines?

My project is a composite project because I want to save the project in multiple files.

Also i want to upload the project to git.

When a testcase gets saved, it saves the entire xml into 1 line xml.

Here are the problems with this:

 - Its very difficult to read

 - Uploading on git and checking the diff is also difficult

 - Debugging anything in the test becomes super difficult

What can be done so that the xml gets saved in accurate xml format and not just one or two lines?
