Don't populate the array buf on the stack, instead make it static.
Makes the object code smaller by over 240 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  21689	  22992	    416	  45097	   b029	cx23885-cards.o

After:
   text	   data	    bss	    dec	    hex	filename
  21348	  23088	    416	  44852	   af34	cx23885-cards.o
