Title: On Windows use git.exe

It has been reported that forcing Magit to use `git.exe` instead of `git.cmd` gives a considerable speedup. I don't know whether that is true but the arguments are sound. So now Magit tries to use `git.exe` but falls back to just `git` (which ends up meaning the `git.cmd` script or so it appears).
