Emacs-28 C Mode: Fontification errors when arglist closing ) is on next line |

Hello, Emacs.
This is (a version of) a bug reported by Bill Sacks <sacks@ucar.edu> in
the correspondence for bug #56818. I am separating it from that bug,
since it is a distinct bug, despite having similar symptoms. In
Emacs-28:
1. Start emacs -Q.
2. Insert the following file in C Mode:
void myfunc(
) {
}
3. In line 2 (the first blank line) type "<TAB>int somevar".
4. Note that somevar is not fontified. This is a bug, given that the
arglist to myfunc is terminated with a ) on line 3.
5. Do something (e.g. typing M-x) to cause a redisplay. somevar gets
its correct face.
6. Note that any insertion or deletion in L2 causes somevar to lose its
fontification. This is a bug.
7. (After 6). Move point onto somevar and do C-u C-x =. This shows
that the face text property is set on the character despite the face
not appearing on the screen.

Thanks for the testing!

No problem! I've now committed the fix to the master branch of Emacs at
savannah, and I'm closing the bug with this post.
