Hi,

The Japanese dictionary bundled with Emacs has a small vocabulary.

For example, to convert "なごや" to "名古屋" (Nagoya) in Kanji, I would
enter "なご" and convert it to "名古", then enter "や" and convert it to
"屋".
Because the Japanese dictionary bundled with Emacs does not have "名古屋
".

The skkdic-convert function in the ja-dic-cnv package generates the
Japanese dictionary, but the logic includes the dictionary vocabulary
reduction process.

So I have created a patch to add an option to skip this reduction
process. I would be happy to receive your review and feedback.
