+	nstrftime: merge glibc strftime changes
+	This incorporates:
+	2019-02-11 Fix a few whitespace arrangement inconsistencies
+	2019-01-24 strftime: Pass flags from "%EY" to "%Ey" [BZ #24096]
+	2019-01-24 Set the default width of "%Ey" to 2 [BZ #23758]
+	2019-01-11 strftime: use the "L_" macro with character literals
+	* lib/nstrftime.c (__strftime_internal): New arg yr_spec.  All
+	callers changed.  Default width of %Ey is now 2.  This is needed
+	for proper handling of Japanese dates starting on 2019-05-01.
+
 2019-02-19  Bruno Haible  <bruno@clisp.org>
 
 	relocatable-prog: Use $ORIGIN trick on more platforms.
