I have just been playing with split screen editing and came across a strange bug with Vintage mode and word wrapping. Basically if one character has wrapped onto the next line I can't get the cursor to move past that line when moving the cursor down the screen. Going up is fine. For example, in the following screenshot I can't get the cursor below that line in command mode with either j (vim down key) or the normal arrow key:

Now it all works fine if I do one of the following things:
* Put it into insert mode
* Move the split so that either no wrapping is happening or move it so two characters are wrapped instead of one.
* Turn word wrapping off
* Disable Vintage Mode
