This seems to do the trick:

  /* If the gap is before the end of the buffer, process the last half
     of the buffer. */
  if (BUF_GPT_BYTE (b) < BUF_Z_BYTE (b))
    sha1_process_bytes (BUF_GAP_END_ADDR (b),
                        BUF_Z_ADDR (b) - BUF_GAP_END_ADDR (b),
                        &ctx);
