/* We want to verify the colorized output of cxx_format_postprocessor,
   but turning on colorization for everything confuses "dg-error" etc.
   The color codes in the generated messages would also need escaping
   for use within dg-error.

   Hence the simplest approach is to provide a custom diagnostic_starter_fn,
   which does nothing.

   The resulting messages lack the "FILENAME:LINE:COL: error: " prefix
   and can thus be tested using dg-begin/end-multiline-output.  */
