[Message part 2 (message/rfc822, inline)]

Subject: 30.0.50; backward-kill-word too eager in cc-mode
Date: Fri, 29 Dec 2023 21:23:54 +0500

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.
