Adapt tutorial to cygwin and add test case
Lacking reliable symlinks, the instructions in the tutorial did not work in a cygwin setup. Also, a few outputs were not correct. This patch fixes these, and adds a test case which follows the instructions of the tutorial (except git-clone, -fetch and -push, which I have not done yet).
