bug#23308: 25.0.92; angle brackects in #include breaks syntax-ppss (c-mode) |

In c-mode (may be in other modes too), lines like #include <stdio.h>
sometimes break (nth 0 (syntax-ppss)), the depth of brackets. This
happens because angle brackets ('<' and '>') in #include lines are
considered to be brackets (which is true) in emacs 25.0.92, but not
in emacs 24.5, where syntax-ppss doesn't break.
How to reproduce:
open a new c file: emacs -Q test.c
Type the following in the file (where | is the point):
#include <>
int
main (void)
{
|
}
Now move between the angle brackets (| is the point):
#include <|>
...
Now type some header names:
#include <stdio.h|>
...
Now check the first value of (syntax-ppss). It is zero.
Now move to some other point (don't press RET). Check the value of
syntax-ppss.
The value is negative when outside of any paren,
