A quoted word that isn't a file name; split parts with two digits

From the re-index's single-file releases:
- A quoted text without an extension ("My \"Official\" remaining set's
  of Inna … 025.jpg [25/74]", "… lr140x16.jpg ( file 046 of 922)
  \"yEnc\"", "\"Dr. Lust\" - … - [12/21] - Ed_DRL_VDR_LM.part09.rar") was
  the file name, the real one stayed in the subject: every file a release.
  It gives way to a file name with an extension beside it
  (nameBesideQuotes); random quoted names with none beside keep theirs.
- Split parts numbered with two digits ("Admiral.EP05.2008.720p.Rus.
  HDCLUB.mkv.21", a.b.movies.divx.russian) share their stem, as .001.
Both implementations; tests; fixtures identical.
