I have my c-mode indentation set up as follows:

(progn
  (setq c-indent-level 4)
  (setq c-continued-statement-offset 4)
  (setq c-brace-offset -4)
  (setq c-argdecl-indent 1)
  (setq c-auto-newline nil))

When I do a ``switch'' in C, emacs indents the case statements
incorrectly.   Similarly, emacs indents my label statements
incorrectly.    Sample:

    switch( foo ) {
      case bar :
	  farf();
	  break;
	  
	case blef :
	    farkle();
	  break;
	  
	  default :
	      printf( "foo bar!\n" );
      }

The correct indentation is:

    switch( foo ) {
      case bar :
	farf();
	break;
	  
      case blef :
	farkle();
	break;
	  
      default :
	printf( "foo bar!\n" );
    }

The problem turns out to be quite trivial.   c-mode doesn't believe
that there can be a space between the label and the colon.  The
following diff shows the required changes to fix this bug:
