Returned value is incorrect in some cases

[jirkaptr]

Improving printf() and its derivatives is very welcome and useful. Unfortunately, I encountered issue in version 1.2.0: The printf() function and its derivatives should return the number of printed (or filled into buffer - sprintf() ) characters. In PrintEx library this is different:

The counters do not count the characters defined by the %n and %p specifications. (I did not test the %r specification.)
