Names: stray quotes, single quotes, hosts, bracketed names; dates, repeats

From the first corpus sweep (183 ranges):
- A stray quote took the last quote pair ('"x.mp3" "Album_BY_WaRLoRD',
  '"x.nfo" " yEnc', '"x.nzb" yEnc"'): the last quoted part with an
  extension is the name. Each file was a release of its own.
- A single-quoted name at the end ("… [001/106] 'You, Me And Dupree.nfo'"),
  not the host before it (www.x2l.nl).
- Text ending in a host ("… www.libranews.nl") is no file name; a name in
  brackets comes first ("[01/77][LIBRATEAM_M2219009.par2]",
  "-^-[Mnozil Brass - Seven.nzb]-^-").
- A leading date is no item number ("09-30-2008_BAK_JRS.r00": a daily
  show's 32,621 files were one release under the poster's tag).
- The file name repeated elsewhere in the subject goes too
  ("(NELET11.par2) [01/58] - "NELET11.par2"").
