Counters: a total padded wider than its index is none; report diff on shared ranges

- "Very Best Of The Who [01/010]", "[02/020]", "[07/070]": a posting tool's
  total of index×10, so every track had a total of its own and was a
  release of its own. A total zero-padded wider than its index is no
  counter ("[001/010]" still is).
- corpus_sweep.py report compares builds over the ranges both replayed (the
  corpus grows between builds).
