Re: charset="Windows-31J"

Hi,

NAKAJI Hiroyuki reported that some Japanese mails use the
`Windows-31J' charset which Emacs doesn't know.  According to
the web pages, etc.[1], it can be treated as `cp932' and
NAKAJI-san contributed a tiny patch to map `windows-31j' to
`cp932' in `mm-charset-synonym-alist'.  I've applied it in both
the trunk and the v5-10 branch.  Thanks NAKAJI-san.
