Summary: possible uninitialized variable in listobject.c:listsort

Initial Comment:
GCC warns that the local variable n in listobject.c:listsort 
might be uninitialized.  I'm not convinced that's the case, but 
it seems that n should only be declared once and should be 
initialized at that point to avoid confusion.  It's both a 
variable local to listsort and a variable local to an embedded 
do/while loop.  It's also not clear that the goto fail statement 
inside the do/while is correct.  Do you intend for n to have 
the value set within the loop?  I think when you get to the 
fail: label you'll see the outer n.
