* progmodes/ruby-mode.el (ruby-encoding-map): Add a mapping from
`japanese-cp932' to `cp932' to fix the problem where saving a source file written in Shift_JIS twice would end up having `coding: japanese-cp932' which Ruby could not recognize. (ruby-mode-set-encoding): Add support for encodings mapped to nil in `ruby-encoding-map'. (ruby-encoding-map): Map `us-ascii' to nil by default, meaning it doesn't need to be explicitly declared in magic comment. (ruby-encoding-map): Add type declaration for better customize UI.
