[PATCH v5 2/5] strftime: Set the default width of "%Ey" to 2 [BZ #23758]

[TAMUKI Shoichi <tamuki@linet.gr.jp>]

The Japanese era name is scheduled to be changed on May 1, 2019.
Prior to this, change the alternative representation for year in
strftime to pad the number with zero to keep it constant width, so
that prevent the trouble we saw in the past from becoming obvious
again from the year after the era name changes onward.

Since only one Japanese era name is used by each emperor's reign as
lately, it is rare that the year ends in one digit or lasts more than
three digits.  In addition, the default width of month, day, hour,
minute, and second is 2, so adjust the default width of year the same
as them, and then the whole display balance is improved.  Therefore,
it would be reasonable to set the default width padding with zero of
"%Ey" to 2.

ChangeLog:

	[BZ #23758]
	* time/strftime_l.c (__strftime_internal): Set the default width
	padding with zero of "%Ey" to 2.
