For future-readiness with AVR or other Arduino targets that use a "PROGMEM" accessor we should have both the "_P" form of the method and the regular (C-string) form. The one that takes FSTR_P should call through to the "_P" version of the method. The use of C-string will actually be the exception and will only apply to strings that are composed (usually because they can be changed at runtime).

Ah, all right, I did it because the function is never called. Now it's more clear for me.
