If I apply the rule to constant variables, let's say AF_INET, is this
the right result?

  1) donwcasing (schemey way I guess)
     -> af_inet
  2) replacing #\_ to #\-
     -> af-inet
  3) omit common prefix. here comes my question, in this case `af-'
     looks like a prefix, how should we treat?
    3.1) omit it
      -> inet
    3.2) expand it (more precise name)
      -> address-family-inet or address-family-internet
    3.3) keep it
      -> af-inet
  4) add '*' as both prefix and suffix. (+ is not a valid before R6RS so
     use * instead)
     -> *${result-of-3}*

If we keep name consisted with UNIX, then take 3.3 process. I'm not sure
what is the best SRFI way or Scheme way. (I believe not 3.1, though)
