It seems like sometimes a slow terminal like lxterminal can take a
little while to respond with the cursor position, so the read can time
out. If it does, a later call to cursor_pos could read it in. To prevent
this, we can call read before even querying the position. If there are
any previous pending status responses, this should hopefully read them
in, and we can abort early without getting confused. If there is no
buffered data on stdin, then it's hopefully safe to write the status
query and read the response.

They say you can always do a better job on the rewrite, and to a certain
extent that was true here. I kept a lot of it the same though, since
there was a lot I liked from the original design. The main improvements
are in efficiency and code clarity.

The editor only repaints when there is a small delay in the input, which
only happens when the user is typing. Otherwise the bytes go straight
into the buffer.

Is this how redo works?
