split mule into three ports:
editors/mule: no language-specific support
japanese/mule-canna: Japanese support, Canna library built-in
japanese/mule-wnn: Japanese support, Wnn library built-in
Note that the two ports under japanese/ will overwrite some of the
emacs support files. Although this itself isn't a problem, if you
pkg_delete it, you will lose some files needed for emacs. (This is
explained in DESCR, although god knows who reads them.)
Also I've listed every single file in the PLIST.
