RichString: do not unnecessarily clean whole buffer

The local stack buffer does not need to be cleaned to zeros when
  - just initialized, cause the length is set to 0 and the first
    character is set to '\0', so all printing functions will safely stop
  - no further used, i.e. the variable goes out of scope
