fix strftime field widths with %F format and zero year
the code to strip initial sign and leading zeros inadvertently
stripped all the zeros and the subsequent '-' separating the month.
instead, only strip sign characters from the very first position, and
only strip zeros when they are followed by another digit.
based on testing by Dennis Wölfing.
