Previsouly, e.g. nl_langinfo(_NL_TIME_WMONT_1) returns "February"
due to the bug. Similarly, nl_langinfo(_LN_TIME_WWDAY_1) returns
"Mon". This patch fixes that.

Hi Takashi,
thanks for catching. The patch is ok, just the commit message
is a bit lacking:

It would be nice to add a description of the actual bug, i. e., the fact
that the bug is an off-by-one pointing into the wide char month and
weekday arrays.
Also
Fixes: d47d5b850bed3 ("Extend locale support to maintain wide char values of native strings")
Please backport to cygwin-3_4-branch as well.
Thanks,
Corinna
