<i18n dev> [11] RFR: 8207152: Placeholder for Japanese new era should be two characters

[Naoto Sato]

Hello,

Please review the changes to the following issue:

https://bugs.openjdk.java.net/browse/JDK-8207152

The proposed fix is located at:

http://cr.openjdk.java.net/~naoto/8207152/webrev.00/

The fix is to simply change the name from "新元号" to "元号". From the API 
standpoint, there is no restriction on the length of a Era name (in 
fact, era names in English localization have more than 2 characters even 
for existing eras). However, it would be desirable to avoid any possible 
unwanted regressions in customer's apps even for the placeholder.
