Also, (I suspect) more commonly, for the rsync protocol used for
git-clone and friends.  See under "Git URLs" in `git help clone`.

If you're installing Git by compiling it from source, which is what I
assume the documentation is referring to, the requirements list is very
small; Git will happily compile without features that require the extra
libraries, just without access to those features.  The version of Git
that's distributed pre-compiled from the Cygwin repository mirrors,
however, aims to be feature-complete rather than having minimal
requirements.  As a result, it pulls in a lot of extra packages that
aren't necessary for basic Git functionality.
