[clang-format] Using Macros breaks before argument in preprocessor conditionals

[Tamaranch]

With

Macros:
  - MY_MACRO(x)=x

this code

#if SOMETHING
MY_MACRO(var);
#endif

is formatted as

#if SOMETHING
MY_MACRO(
var);
#endif

which is probably unexpected.

With ```yaml Macros: - MY_MACRO(x)=x ``` this code ```c #if SOMETHING MY_MACRO(var); #endif ``` is formatted as ```c #if SOMETHING MY_MACRO( var); #endif ``` which is probably unexpected.

Cannot reproduce with any version. Please provide more info, like clang-format version and other config options if they are used.

Oh sorry, I forgot the version this time: it's 17.0.6.
No additional option is needed to reproduce it, however I realize now that you need an #if-#else-#endif above in the test file, even empty:

#if
#else
#endif

#if SOMETHING
MY_MACRO(var);
#endif
