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.

Hello Paul-san,

Thank you for your porting Glibc strftime changes to the
implementation in Gnulib.

Let me just make a few comments to make it better code.

For the implementation of nstrftime.c in Gnulib, upcase is added as an
argument of __strftime_internal function compared to strftime_l.c in
Glibc.

This (upcase) argument is used mainly for the process described in the
beginning of format_char, such as %a, %A, %[bh], %B, etc.

On the other hand, tzset_called argument is used in the process
described at the end of format_char, i.e. %z.

Therefore, I think these arguments are in this order.

Since yr_spec argument to be added this time is used in %EY and %Ey of
format_char, it is better to make the argument order the same.

Recommend instead:
