I never thought about such a situation actually; I think that that init 
help function might be made public and callable from outside

please, do not ask for that ;-) ;-)
this behavior was requested by other users and it was quite a nightmare 
to implement it, so I wouldn't want to go back ;-)

I'll try to handle this matter soon.
