Because he is no longer able to see the cursor: he has
> no idea about where it is located on the screen.
Sorry, but to be totally lost is something completely different, the
user just has to move the cursor. There are not many invisible
characters anyway.
BTW, I have tried several color schemes in my console Vim (dark and
light ones) and I could always see the cursor being located at a bar (I
am using Windows XP). It may depend on the type of the console.
Best wishes,
Georg
