  get real results after all checks.

Remove two FIXME's

  Check for NULLs only if we don't replace column results,

    (see bug #14254: func_crypt.test fails on FreeBSD with --ps-protocol).
  
  Remove FIXME comments since it ssemd like the function handles vertical displays and 
  even wheter the string is terminated or not is not relevant since we only append
