7.1: to_char(): Y,YY,YYY,YYYY fix

Applied. Thanks

Hi,

here is a patch for formatting.c (to_char/timestampt()), for 7.1
it fixing Y,YY,YYY,YYYY conversion, the docs and regress tests update
are included too.

During the patch testing I found small bug in miscadmin.h in
convertstr() declaration. Here it's fixed too.

Thanks

Karel
