Makes sense, but out of curiosity, why is the cursor hidden *immediately* when I clear t_ve, even when no text is being drawn? Even if I do the `set t_ve=' in a silent mapping (to ensure no text is being changed), the cursor disappears immediately. I'm actually glad it works this way - I just want to be sure it's intended behavior, and not likely to change...
