strftime: Pass the additional flags from "%EY" to "%Ey" [BZ #24096]
The full representation of the alternative calendar year (%EY) typically includes an internal use of "%Ey". As a GNU extension, apply any flags on "%EY" (e.g. "%_EY", "%-EY") to the internal "%Ey", allowing users of "%EY" to control how the year is padded. Reviewed-by: Rafal Luzynski <digitalfreak@lingonborough.com> Reviewed-by: Zack Weinberg <zackw@panix.com> ChangeLog: [BZ #24096] * manual/time.texi (strftime): Document "%EC" and "%EY". * time/Makefile (tests): Add tst-strftime2. (LOCALES): Add ja_JP.UTF-8, lo_LA.UTF-8, and th_TH.UTF-8. * time/strftime_l.c (__strftime_internal): Add argument yr_spec to override padding for "%Ey". If an optional flag ('_' or '-') is specified to "%EY", interpret the "%Ey" in the subformat as if decorated with that flag. * time/tst-strftime2.c: New file.
