The strftime function works incorrectly, in cases where the Format string part on the maxsize Bound, is not a %-placeholder, but rather some "normal" text.  Attached example program "arduino_test.ino" demonstrates the Problem.  There are two error Symptoms:
1)  max Buffer size is exceeded
2)  actual amount of written Bytes/Chars ,  Reports a wrong value

file #48513: arduino_test.ino
