Names: split rar volumes; a file's size in brackets after its counter

- "rld-gtre.r13.002": a split volume after a rar volume is stripped like
  one after .rar (usenet-town's posts were 1,620 single files).
- "[26/32] - [4929] "…part24.rar"": the bracketed size after the counter
  goes (Kingdn's episodes, 2,850 single files).
