Description

Defining a function-like macro with the `Macros` option in `.clang-format` and then using it within a function declaration allows one extra space to remain, even when it shouldn't. However, it will not add a space if one doesn't already exist. (tested on 8e90208)

`.clang-format`:
```yaml
Macros:
- X(x) = x
```

Case 1 (works as expected)

`test.c`:
```c
#define X(T) T
void a(X(int) *b) {}
```

Running `clang-format` has no change, as expected.

Case 2 (fails, extra space is kept)

`test.c`:
```c
#define X(T) T
void a( X(int) *b) {}
```

Running `clang-format` has no change, but it should remove the extra space between `(` and `X`. If more spaces are added between `(` and `X`, then running `clang-format` removes all but one space.

Log with -debug (expected, case 1):

```
