Refs #913. The last 2.8 title batch: chancellor alone. judge was measured with it and stays a title.

What changes

• chancellor gains a dated given reading (US SSA 2,648 births, Census rank 7,974), so it is a title only inside a title phrase (rules/H9, the title phrase).

  • Chancellor Smith, Mr Chancellor Smith and Smith, Chancellor read given Chancellor. 1.4.0 through 2.7.0 read the title.
  • Vice Chancellor, Associate Chancellor and Chancellor of the Exchequer keep the title.
  • Vice Chancellor and Lord Chancellor are listed phrases, so a bare Chancellor opening a name reports title-or-name, as Dean Smith does.

• New attaches data for the phrases a modifier does not reach:

  Word	Attaches to	Keeps
  lord	chancellor, justice	Lord Chancellor, Lord Justice
  lady	justice	Lady Justice
  deputy	the office kind, as chief does	Deputy Chancellor, Deputy Judge
  pro	chancellor	Pro Chancellor
  magistrate	judge	Magistrate Judge

• Lord Justice and Lady Justice fix: Lord Justice Leveson and Lady Justice Arden now read title Lord Justice and Lady Justice. Every release from 1.4.0 through 2.7.0 read title Lord, given Justice.

• judge stays a title. Measured as a contested title, it broke 13 FEC records, every one a judge filing FAMILY, JUDGE …, against 2 fixes across all local corpora. Its counts are recorded in the note on its title reading, so a later batch meets the evidence.

Cost (accepted)

• A chancellor written with the bare title reads it as the given name: Chancellor Merkel gives given Chancellor, family Merkel.
• John Smith, Chancellor reverses to given Chancellor, family John Smith. This is the role-word class already accepted for John Smith, Dean.
