Subject: [PATCH] implement wcsftime padding specifier extensions
Commit 8a6bd7307da3fc4d08dd6a9277b611ccb4971354 added support for
padding specifier extensions to strftime, but did not modify wcsftime.
In the process, it added a parameter to __strftime_fmt_1 in strftime.c,
but failed to update the prototype in wcsftime.c. This was found by
compiling musl with LTO:
src/time/wcsftime.c:7:13: warning: type of '__strftime_fmt_1' does \
not match original declaration [-Wlto-type-mismatch]
Fix the prototype of __strftime_fmt_1 in wcsftime.c, and generate the
'pad' argument the same way as it is done in strftime.
