I think that this should be split into two patches immediately.

The "%-EY"/"%_EY" could go in as a bug fix right away.

The default for padding needs more review but could be given an exception
while we review the patch. I think both the patches should go in to 2.29, 
but need a little more work as Paul Eggert suggests.

They are important changes to get into 2.29 because of the Japanese Era
name change. Once the patches are in master they will allow the later
patches in April to be applied once the Era name is announced.

These changes are important to downstream enterprise distributions, but
in that case we only care that they land in master at some point. We want
a canonical solution that everyone is using.

The new Era name will likely have to be backported to all the active
open stable branches so they can display the new Era name.
