Am I the only software developer so far who would dare to reconsider
implementation details from three status functions?

No.

Thanks for this kind of promising feedback.

But we're waiting for you showing is that it is an improvement.

Can this aspect also be clarified to some degree from a logical point of view?

* Would you really like to know under which circumstances data processing
  will be faster for a single character instead of using a string pointer
  and corresponding two characters?

* Do you care for a changed memory allocation characteristic?

* Will it occasionally be useful to avoid the storage for another string literal?
