ISSUE-447: Add MS932 as a label of Shift_JIS

Add MS932 as a label of Shift_JIS

This issue tracks the bug listed above and was created as part of the WG CR process.

--- shows an email failure
when using Encoding Standard label resolution for processing incoming email,
because MS932 is not recognized as a label of Shift_JIS.

According to a Wikipedia pages linked to from the comments on that bug, Java
started recognizing the label windows-31j in JDK 1.4.1. Nowadays Java uses IANA
preferred names and treats MS932 as an alias for windows-31j, which is the
preferred name. The theory is that email labeled MS932 arises from MS932 having
been the Java-recognized way to name the Windows-flavor of Shift_JIS in legacy
Java. indicates that
Presto-Opera supported MS932 as a label of Shift_JIS. (And apparently also
supported the cp932 label, which the JDK doesn't know about.)

Although, we don't have a Web-motivated indication justifying the introduction
of ms932 as a label of Shift_JIS, it seems probably harmless and might fix more
than the one email that has been reported.
