In a previous version of the glyph statistics, which 
  treated (qoe) (qor) (oe) (or) as prefix+(e), I noticed
  a curious coincidence: the counts for (bg) and (g) were amost equal to
  those of (o) and (qo), respectively.  Is there a correlation?
  intra-word or inter-word?  (Currier had noticed something like
  it, but he didn't say the numbers were so close!)  
  
  Let's check:
  
    cat .voyn.glp \
      | sed \
          -e 's:([_/=]*)::g' \
          -e 's/([b]*g)([^)]*)/@&@/g' \
      | tr '@' '\012' \
      | egrep '^\([b]*g\)' \
      | sort | uniq -c | expand \
      | sort +0.0 -0.7nr \
      | compute-freqs \
      > .voyn-bg.frq
  
    cat .voyn.glp \
      | sed \
          -e 's:([_/=]*)::g' \
          -e 's/([^)]*)([q]*o[er]*)/@&@/g' \
      | tr '@' '\012' \
      | egrep '\([q]*o[er]*\)$' \
      | sort | uniq -c | expand \
      | sort +0.0 -0.7nr \
      | compute-freqs \
      > .voyn-qo.frq
      
    compare-freqs \
        .voyn-bg.frq \
        .voyn-qo.frq \
      > .voyn-bg-qo.cmp

  So the correlation is not inter-word.  Perhaps intra-word?

  So the correlation does not seem to be intra-word either. Boh.
