citefind: a name that ends in an initial, and the imprint after it

The stop after `P.` is an initial rather than a sentence stop, so `Hoyt,
Edwin P. The Supersalesmen. New York: World Publishing, 1962.` never got cut
there. The name came back as `Hoyt, Edwin P. The Supersalesmen` and the next
segment along — the imprint — became the work. Both fields wrong from one
missing cut.

An inverted name whose forenames end in an initial, with two or more words
after it, now ends at that initial. Two words, because one is a forename:
`Price, M. Philips` and `Drexler, K. Eric` are whole names and must not be
cut.

And the segment the reader settles on for a title may not be an imprint —
which is what the function has said it did since it was written, in a comment
above a predicate that never checked. Asked narrowly enough that a title with
a colon in it survives.

On 199 reference chapters never used for tuning, imprints stored as the work
fall from 376 to 55, and the share of rows naming an author rises from 86.1%
to 88.1%.
