I'll be happy to both fix things pointed by Steven and try some other approach, 
if that's required, but I would rather do it after a consesus is reached, so I 
don't have to do the same stuff several times (changing argparse tests requires 
some work - it's really awesome test suite).

What about optparse? Maybe there we can add this option without much thinking, 
by checking if help-options is used at the end of parsing? If not, we face the 
same problem as with argparse.

I don't really understand, why can't we just check if help-options is provided 
by the user and add our own, if it is not? Even if options are parsed several 
times (when doing some debugging I have seen my messages printed multiple times 
in help formatter), we should be able to inspect options in raw form and 
determine, whether --help-options is used.
