Hi all,

After running the following snippet, resizing my Emacs frame to be narrower than ~18 characters causes Emacs to freeze.  This seems to be because the wrap-prefix is too wide to be displayed unbroken.

(with-current-buffer (get-buffer-create "*wrap*")
  (visual-line-mode)
  (dotimes (_ 50)
    (insert "Some long prefix: ")
    (insert (propertize "Some text that wraps, thanks to a wrap-prefix property"
			'wrap-prefix "                  "))
    (insert "\n")
    (pop-to-buffer (current-buffer))))

Clément.
