/**
 * Ellipsizes a string near a word boundary.
 *
 * An ellipsized text looks much better if the ellipsize was added at the end of
 * the last full word instead of somewhere in the middle - especially if there
 * are very few characters remaining.
 *
 * @example
 * ellipsize('one two three four', 8);
 * // 'one two…'
 *
 * ellipsize('one two three four', 100);
 * // 'one two three four'
 *
 * ellipsize('12345678910')
 * // '1234567…'
 *
 * ellipsize( 'one two&three four', 8, { chars: [' ', '&'], ellipse: '→' });
 * // 'one two→'
 *
 * // its default settings
 * ellipsize( '123456789ABCDEF', 8, { truncate: true });
 * // '1234567…'
