  Log:
  When skipping input data, don't overflow a 32-bit size_t.
  This can only happen on 32-bit systems when you're reading
  an uncompressed archive and the skip request is an exact
  multiple of 4G (e.g., skipping a tar entry with an 8G body).
  
  The symptom is that the read_ahead() ends up returning zero
  bytes, and the extraction stops with a premature end-of-file.
  
  Using '1' here is more correct anyway, as it allows read_ahead()
  to function opportunistically and minimize copying.
