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.
