This shows that with the "--keep" option, changes that are both in
the work tree and the index are kept in the work tree after the
reset (but discarded in the index). As with the "--merge" option,
changes that are in both the work tree and the index are discarded
after the reset.
In the case of unmerged entries, we can see that
"git reset --merge HEAD" is disallowed while it works using
"--keep" instead.
And this shows that otherwise "--merge" and "--keep" have the same
behavior.
