Incorrect faces on display

[Stefan Monnier]

I started seeing recently problems where elisp code gets displayed with the
font-lock-comment-face even though it's not a comment.

This always shows up right after an invisible piece of text (I use
outline-minor-mode in elisp).

I first thought it was some funny bug in font-lock or jit-lock, but a quick
C-u C-x = shows that the text-properties are correct: the problem is in
the redisplay.

I finally came up with a recipe to reproduce it:

   emacs -Q -f global-font-lock-mode -f outline-minor-mode

   (; RET a RET (foobar C-u 1000 M-x hide-sublevels

If all goes well, you'll see that the second line displays "(foobar" using
font-lock-comment-face.
