Commit 9e8eceab ("Add 'merge' mode to 'git reset'", 2008-12-01),
added the --merge option to git reset, but there were no test cases
for it.
This was not a big problem because "git reset" was just forking and
execing "git read-tree", but this will change in a following patch.
So let's add a few test cases to make sure that there will be no
regression.
