It would have been helpful to explain that the split did not break
anything because the other half of the split started using a new and
different proprocessor macro before saying "Let's fix".

It would have been "broken" that needs "fixing" if two headers
inherited the use of the same _HDR_H preprocessor macro, of course.

The patch obviously looks good.
