[Bug-gnu-utils] Bugfix patch for patch :)

[Javier Kohen]

Hi!

I was applying the patch to upgrade XFree 4.0.0 to 4.0.1, but patch Seg Faulted.
I did some digging on the code and found that when using Plan A, sometimes, 
re_input() was being called without having previously invoked scan_input() to 
init the buffers. The result was it trying to free twice the same memory 
location.
The patch attached modifies re_input() so it doesn't free twice the same memory 
block. I did it this way instead of trying to change the whole logic in patch.c 
for simplicity reasons, but note that I don't know if a similar problem could 
affect Plan B.
