Log:
  bectl(8): initialize reverse earlier
  
  This turns into a warning in GCC 4.2 that 'reverse' may be used
  uninitialized in this function. While I don't immediately see where it's
  deciding this from (there's only two paths that make column != NULL, and
  they both set reverse), initializing reverse earlier is good for clarity.
