Description copied from interface: Command

The same answer as Command.mandatoryFirstTokensSlow(), written by hand so that it costs nothing to get. Returning null (FirstTokens.ANYTHING) means "I can match any line" and keeps the command in the list tried for every token nobody claimed. That is the safe answer: a command that declares too much only costs the regex attempts it could have skipped, while one that declares too few of its tokens stops being reachable for the ones it left out. A non-null set is never empty in practice: it would mean the command matches no line at all.
