* bug#68111: 30.0.50; backward-kill-word too eager in cc-mode

In cc-mode (C lang files) calling backward-kill-word seems to be too eager. For example, given the following file and cursor position:

```
int main() {
   printf("alpha beta gamma<cursor>
}
```

calling backward-kill-word results in

```
int main() {
   <cursor>
}
```

while the expected result is probably:

```
int main() {
   printf("alpha beta <cursor>
}
```

It seems that this is a regression in commit dae8aab52874441a70a94435d50f25b27301d9b0, by Alan Mackenzie on 2023-06-21.
