More per-file suffixes: old rar volumes, .rev, a part's par2, .bc; a size after an unquoted name

Each file of these uploads was a release of its own:
- "BD_NoTHing018.s41", "…CyjI.s00": rar volumes after .r99 (as the file's
  own lower-case extension only, so "show.s01.rar" keeps its season);
- "chappelle1.part02.rev": rar recovery volumes;
- "X.part1.par2", "X.part1.vol00+34.par2" beside "X.part1.rar";
- "NZPEC….180.bc": BCArchive volumes;
- "[27/70] - 2407.jpg - 28": the size in kB after an unquoted name.
