calloc.c nit

[Jim Meyering]

I've just checked in this change
to make the code agree with this comment:

  /* Allocate and zero-fill an NxS-byte block of memory from the heap.
     If N or S is zero, allocate and zero-fill a 1-byte block.  */

2005-06-16  Jim Meyering  <address@hidden>

        * calloc.c (rpl_calloc): Allocate a 1-byte buffer (not 1xS or Nx1)
        when either N or S is zero.
