emacs -Q

;; please paste this line:

i i Turchi spezzano la resistenza a sud i resiste solo Clissa (difesa

;; to get the "right" lenght of the line

M-x text-mode
M-x flyspell-mode
M-x longline-mode

type <space> and 2 letters

<backspace> <backspace> => error (it can't go to the previous line without
error

=> long-line doesn't wrap lines anymore, flyspell lost fontifycation...
It needs a restart both of longlines and flyspell

Regards

Marco
