Until now, NamespaceEndCommentFixer was adding missing comments for every run,
which results in multiple end comments for:
namespace { int i; int j; } #if A int a = 1; #else int a = 2; #endif
result before:
namespace { int i; int j; }// namespace // namespace #if A int a = 1; #else int a = 2; #endif
result after:
namespace { int i; int j; }// namespace #if A int a = 1; #else int a = 2; #endif
