As I'm sure you'll hear again, readline assumes that it knows where the
physical cursor is on the line, and to assure this assumes it starts with
the cursor in column 0. The redisplay code assumes this. There is no
portable way for readline to determine the physical cursor location, so
it has to make assumptions.

There are various imperfect workarounds, but the easiest one is to hit
return.
