That's a preliminary patch to encourage improving the matter,
I suspect there might be some unhandled side-effects in some
perticular cases, when using arbitrary cursor movement
for example, though it's unclear if those should be handled
separately or not.

Would you have a suggestion about how to handle cursor absolute
position with text position, maybe we need some addition state?
