Steps:
- Set 'Options|Editing|Indentation Engines|C++ Indentation Engine|Add Space Before Parenthesis' as True
- Open in editor this C++ code:
-----------------------------------
#include <stdio.h>
#define M(x) puts(#x)

int main() {
    M("test");
    return 0;
}
-----------------------------------
- Call context menu in editor and select 'Format' menu item
==> After 'Format' I see wrong code in editor (I cannot build this code)
#include <stdio.h>
#define M (x) puts (#x)

int main () {
    M ("test");
    return 0;
}
