[Peter Kjellerstedt]

This avoids the following error:

  src/devices/grohtml/post-html.cc: In member function 'void
  header_desc::write_headings(FILE*, int)':
  src/devices/grohtml/post-html.cc:1402:32: error: format not a string
  literal and no format arguments [-Werror=format-security]
      fprintf(f, buffer.contents());
