Plan step 38 review: a %00 in the asset path reached realpath(), which
throws on a null byte, so the route answered 500 instead of 404; a
directory whose name ended in a served extension would have reached
response()->file(). Both 404 now. The tests add what the review
probed: encoded dot segments and slashes, backslashes, absolute paths,
a directory, a very long path and a symbolic link pointing out of a
served folder, all 404.
