minimize tests: Require newline before EOF

A final newline is automatically inserted by many traditional unix tools and
editors, which makes editing .mini files rather hard with e.g

 - vim, emacs,
 - `copar minimize foo.input > foo.mini`.

All of the above insert a trailing newline automatically.
