Hi emacs-devel,

IIUC the proper way in Emacs 25 to signal changes that require a refontification to font-lock is to call font-lock-flush. This doesn't always do as much as font-lock-fontify-buffer does, though.

In particular, when the font-lock-fontified variable is nil (which does happen, though I don't know why; I don't know what this variable is for), then calling font-lock-fontify buffer does refontify the whole buffer, but font-lock-flush and font-lock-ensure don't seem to do anything.

What's the proper way to mark a buffer for refontification (and refontify the visible portion) immediately in 25?

Thanks,
Clément.
