[XeTeX] hyphenating words with hyphen

I don't think the m-dash is "often too wide": it is defined by the length of
"m" in the particular font. I think you wanted to say that you don't like
the size of an m-dash and want an in-between-n-and-m-dash (now that's
something for hyphenation :-)). I'm not sure if this is good typographical
practice, though.
