It appears that when this test is executed 'insertmode' is set.
The test itself doesn't do that, so it must be a leftover from another
test that failed. Try commenting out other tests, such as
Test_edit_08() and others that mess with 'insertmode' to find out which
one causes 'insertmode' to be set.
Or add ":set noim" at the end of every test function. Then hopefully
the test finishes and tells you which one failed.
