    emacs: use _ as a word break with word movements
    
    This uses our new (regained) ability to move by words that are broken
    by _. This is how word breaks are implemented in emacs and they seem to
    like it. One argument was that GNU naming used underlines because of
    emacs doing this (or vice-versa, who really knows).
