chunkmd: a bibliography converted into a bulleted list

An entry opening was a surname at the start of a line, and a converted
bibliography is often a bulleted list — so the bullet sat exactly where the
surname was looked for and not one entry was seen:

    •   Skorupski, J. 1995. 'Agent-Neutrality, Consequentialism,
        Utilitarianism', Utilitas, 7: 49-54.

The whole page went unflagged, no chunk of it was ever selected, and books
whose only bibliography arrived this way came back with no citations at all.
A bullet may now stand where the surname would.

Measured against the corpus: of 300 sampled body chunks that open lines on a
bullet and an inverted name, 0 were flagged before and 223 after. Across
3,000 randomly sampled unflagged body chunks, the change fires on none — it
buys the bulleted list and nothing else.
