I am using emacs ediff to compare two files that I frequently update. How can I refresh or update the buffer to reflect the new file without killing and reloading ediff? When I try to update each file using C-x C-v, the Ediff Control Panel says "You have killed a vital Ediff buffer--you must leave Ediff now!"
Switch to the Emacs Ediff control panel and and press !
.
That will do it.
