`c-indent-command' in a rare case

Create a new C mode buffer and type 

	#define X\ TAB

in it (note: no RET.)  Emacs will hang in `c-append-backslashes-forward'
till you press C-g.  The one-liner below solves this.  However, I'm not
sure if this the correct way of solving.  Should `(forward-line 1)'
return 0 when not advancing a single line and only jumping to the end
of last, unterminated, line?
