They are pretty git friendly. There's instructions floating around for how to do it but it basically works as you'd expect once you get your .gitignore file set up properly.

The Editor loads assemblies dynamically as well so you can branch/checkout and the Editor will automatically recompile everything without a restart.

Only problem I've had is with scene objects but I think I recently fixed that once with a tweak to my .gitignore.
