Let's do the same nolint here.

[kozy, 2016/09/24 01:35:55]

Done.

+  String16(const char* characters)  // NOLINT(runtime/explicit)
       : String16(characters, std::strlen(characters)) {}
   String16(const char* characters, size_t size) {
     m_impl.resize(size);
     for (size_t i = 0; i < size; ++i) m_impl[i] = characters[i];
   }
