Mordante added inline comments.


================
Comment at: clang-tools-extra/clang-tidy/bugprone/ReservedIdentifierCheck.cpp:70
+                                      const bool IsInGlobalNamespace) {
+  return IsInGlobalNamespace && Name.size() > 1 && Name[0] == '_';
+}

Ok. I think a separate patch will be better.
