> Problem:    Test 75 fails on MS-Windows.
Solution:   Use :normal instead of feedkeys(). (Michael Soyka)

Just changes the tests, so not reason not to include this patch.

Marked 430 as NA because it's only relevant to vim not compiled with `-conceal` and no plugin writers will probably check that we have it.
