/**
 * Read one option word, or null when the word is an operand.
 *
 * This is bash's `set` grammar, which shell startup speaks too: a sign,
 * then either `o` naming an option in the next word or a cluster of
 * single-letter options, where `-` turns them on and `+` turns them off.
 * `bash -x file` and `set -x` therefore cannot disagree about what `-x`
 * means, and an option one of them learns the other gets.
 *
 * `-`, `--` and a `--long` word are not option words. The first two end
 * option parsing and the third belongs to whoever declares long options,
 * so both are the caller's to answer.
