Version control of Mathematica notebooks

It's recommended to disable the file outline cache, which is the metadata you're referring to when you look at the notebook with a text editor. As you discovered, it can cause merge conflicts if multiple parties are editing the same notebook.

In the Mathematica menu, go to Format → Option Inspector..., in the top-left set the scope dropdown to Selected Notebook and search for FileOutlineCache in the search field. Set the option to False and save your notebook, and you should be all set.

Note that this can make opening notebooks a little slower, but unless the notebook is rather large, you probably won't notice the difference.
