  !
  ! If a show_* line ends with VARS=... where '...' is a comma
  ! separated list of variable names, these variables are assumed to
  ! be part of the call line, and will be expanded by the test script,
  ! for example:
  !

  ! In this example the test script will automatically expand 'x' and
  ! 'y' in order to better test different aspects of GDB.  Do take

  ! with other text on the line, in the example above, avoid variables
  ! named 'some' or 'array', as these will likely clash with
