I could reproduce the error when using bash 4.3.  The main difference in
versions seems to be that bash-4.4 repaints the last line of the prompt
in reponse to the resize event, whereas bash-4.3 doesn't respond to that
event; it just waits for the next user input.

Although I never got this short string.  I always get
"\015\033[K<prompt>\015\n\032/<path>\015\n<prompt>".  Not really that
important, it's just kind of tickling my curiosity.

Anyways, pushed the fixed to emacs-26.
