 * @param enemy_count      Incremented for each enemy uncovered (excluding known_units).
 * @param friend_count     Incremented for each friend uncovered (excluding known_units).
 * @param spectator        Will be told of uncovered units (excluding known_units).
 * @param instant          If false, then drawing delays (used to make movement look better) are allowed.
 *
 * @return whether or not information was uncovered (i.e. returns true if any
 *         locations in visual range were fogged/shrouded under shared vision/maps).
