Subject: for-loop indentation after cast at left margin

In GNU Emacs C-mode, there is an indentation error in the following
situation:

	  (void)strcpy(whoami, *argv++ ); 
	  for (i = 0; i < r; i++) 
	    x[r] = i;

(The details of the loop control and contents are irrelevant.)  I have
indented the loop contents correctly.  But C-mode indents it like this:

	  (void)strcpy(whoami, *argv++ ); 
	  for (i = 0; i < r; i++) 
	       x[r] = i;

If the loop contents are enclosed in braces, indentation is correct.  If
the cast of the function is removed, or if it is indented at all,
indentation is correct.  But after a function cast beginning in the left
margin, unbraced (one-statement) for-loops are incorrectly indented.  The
loop need not be directly after the cast for this effect to occur: its
effects extend indefinitely, even beyond the scope of the main(){...} that
encloses the cast.

The scope of the bug may be wider than I have described, but this is what I
have observed.
