Bug#789130: bsdmainutils: [ncal] prints wrong week number

[Sergey Romanov]

Weird. I'd never expect C and C.UTF-8 be different. These are locale values:
$ LC_ALL=C locale week-1stweek
4
$ LC_ALL=C.UTF-8 locale week-1stweek
7
$ LC_ALL=en_US locale week-1stweek
7
LC_ALL=en_US.utf8 locale week-1stweek
7
$ LC_ALL=de_DE.utf8 locale week-1stweek
4
$ LC_ALL=ru_RU.utf8 locale week-1stweek
