It's difficult and error-prone to sort these messages statically because 
there's no obvious to know where to insert the new value without reading 
lots of help strings from other commands. You could argue that we could 
sort by variable name but it feels like an unnecessary burden on the 
developer to maintain this sorting order when we can just automate it at 
runtime without giving up anything.
