Martin von Zweigbergk d6622e5d42 tests: make fake editor scripts initially empty
I would expect `set_up_fake_[diff_]editor()` to create an empty script
but it turns out they didn't even create the files. That means that
the caller needs to write an empty script to them if they want the
fake editors to not do anything. Let's instead write the empty
scripts, for a less surprising behavior.
