The builtin "help" only gives you a short summary of a single command's options. It is not an exhaustive reference. For the complete story, you must read the man page, or the web-based reference. It would be completely ridiculous if "help history" were to print out a synopsis of every history-related shell variable, and mention every other command that could possibly interact with history in some way.
