Sorry. For some reason I used to get `git help ...` redirect me to the (URL of) the actual website.
I think the file:/// is so that you can fire off "[cmd /c] start FILEPATH" to load the default browser, while also not having to worry about spaces in the path.
What? Is the intention, that I access your C: drive? Also is it common to have a file:// link on MS Windows? I thought this was a unix thing.
