 * Return an array of ids that represent all the usable combinations that a user could enter.

 * For example, if the command ids are:
 * - foo:bar:baz
 * - one:two:three
 * Then the usable ids would be:
 * - foo
 * - foo:bar
 * - foo:bar:baz
 * - one
 * - one:two
 * - one:two:three
 *
 * This allows us to determine which parts of the argv array belong to the command id whenever the topicSeparator is a space.
