Clarification in the docs about clac HOT 2 OPEN

You are absolutely right, I think we should definitely clarify that paragraph and perhaps mention in a succint way what's the behavior for each group of commands. Maybe writing a note for each and every command will make the it too verbose, so we will have to think about how to redact it best. I'm glad you took the time to read the documentation carefully, thanks for spotting this :-)

An easy and consistent solution would be to simply add the guard by count to the functions that don't have it right now, so that they also become no-ops. I mean something like changing

else if (!strcasecmp(word, "sum")) {
	push(s0, add(s0, count(s0)));
}

to

else if (!strcasecmp(word, "sum")) {
    if (count(s0) > 0) {
	push(s0, add(s0, count(s0)));
    }
}

This would change the behavior to make sum (and the others) a noop instead of default to zero, but it'd be consistent and that behavior seems intuitive to me. Not sure if that's what you want, but it's what I would suggest.
