[clang-format]: macros can cause formatting to remove spaces

[proximities]

macros can cause formatting to remove spaces sometimes. for example

   for (auto [name, format] : targetMap)

is fine, but with a macro #define var auto, clang formats behaves like this

   #define var auto
   for (var[name, format] : targetMap)
