citefind: a note that remarks first and cites second

The bar a guessed title has to clear was waived when the entry also gave up
a container, on the reasoning that a container vouches for the rest of the
reading. Auditing the corpus rather than the reference chapters showed that
is wrong, and wrong on the commonest note there is:

    As Lewis White Beck has rightly put it. See his Early German
    Philosophy (Cambridge, Mass., 1969), p. 439.

The remark opens, the citation follows, and the second sentence becomes the
container — so the first was stored as the work and the book named in it was
lost. Neither a siglum nor a remark is the name of a work now, whatever else
came off the entry.

Measured where these notes actually live, which is flagged body chunks
rather than bibliography chapters: on the corpus the class ran at 1.43% of
rows naming a work. The cost is 46 rows in 34,359 on the reference holdout,
where the share naming an author rises from 88.1% to 88.2%.
