<pre>
    I was referred here to post a potential bug in the clang-format application.

I am running Ubuntu 24.04. The version of clang-format is:

```
$ clang-format --version
Ubuntu clang-format version 18.1.3 (1ubuntu1)
```

I use this file:
```
#include <stdio.h>
#include <compare>

int main() {
  int x = 5;
  int y = 6;

  if ((x <=> y) != 0) {
    printf("x is not equal too y\n");
  }
}
```

I can compile and run it.

```
$ g++ -std=c++23 spaceship_test.cpp
$ ./a.out
x is not equal too y
```

I then run clang-format and try to compile:
```
$ clang-format -i spaceship_test.cpp
$ g++ -std=c++23 spaceship_test.cpp
spaceship_test.cpp: In function ‘int main()’:
spaceship_test.cpp:11:13: error: expected primary-expression before ‘>’ token
   11 |   if ((x <= > y) != 0) {
      |             ^
```

Indeed in the file the <=> has been changed to "<= >" Notice the space symbol after the "=".

```
#include <stdio.h>
#include <compare>

int main() {
  int x = 5;
  int y = 6;

  if ((x <= > y) != 0) {
    printf("x is not equal too y\n");
  }
}
```

Here is the clang-format file I am using [clang-format.txt](https://github.com/user-attachments/files/18414723/clang-format.txt). I had to add a .txt in order for the tool to accept the .clang-format file


I assume this is some sort of bug in clang-format.

Thanks
Chris
