- Removed calls to getchar() in fatal error handling code when either
  template or output worldfile could not be opened.  The calls to
  getchar(), the return value of which was not being used, caused
  g2w to block forever waiting for input instead of exiting with an error.
  This made it impossible for programs that call g2w to detect the error
  condition.
