As far as I'm aware the "-nw" display is implemented the same as any
other platform. For the record I can't see these problems on GUI emacs
on the mac, but I do see them in the terminal using iTerm2.

It looks like sometimes the display is incorrect, and other times the
action actually changes the underlying buffer contents in an
unexpected way.
