Fixes for some style bugs in the initial version of this file:

- missing reformatting protection in copyright.
- missing blank line after copyright.
- unusual spelling of idempotency macro (no trailing underscore).
- unusual value of idempotency macro (1 instead of <empty>).
- space instead of tab after #define's.
- unnecessary namespace pollution and extra code to give it.
- tab instead of space after #endif.
