When using CMake to generate the files required to build Git in Visual
Studio, a bunch of files are generated. We will want to prevent them
from being tracked in Git.

If we were to go this route, let's

 * update the log message to say that we assume we will use CMake to
   build in-place.

 * update the comment in the top part of the CMakeList.txt that
   suggests it is a possibility to use it from subdirectories.

 * optionally, update the same comment to recommend "clean -xdf"
   as a way to bring the source tree back to the pristine state.

Will queue with a tentative attempt to do the first bullet point to
save one roundtip, something like:

    When using CMake to generate the files required to build Git
    in-place for Visual Studio, ...

Other two points needs help from others (iow, I won't do so myself
right now).

Thanks.
