Yes if this function was actually BSD-like, but newlib strftime supports all the 
POSIX and GNU flags (including +, which was why why I couldn't add BSD %+ for 
default locale formatting), so I thought I should add POSIX extended year 
handling to support the extended year range and formats required, for 
compatibility with other %Y formatting in that function, and tests of that 
functionality.
