User:Certes/Reports/Talk with missing parent ns

Possibly orphaned talk subpages: parent missing, in non-article namespaces, from query/62347. (In complex cases like Talk:a/b/c/d, neither Talk:a nor Talk:a/b/c exists.) Excludes User_talk:123.45.67.89/Subpage and User_talk:Foo/Subpage, as it's common (6000+ cases) to create subpages without a main user talk page.
