This one turned out easy.
I assume what you had in mind was something like the attached.

With this the help entry present is no loger tha last one seen but the one belonging
to the menu (the symbol used within that menu).
So if I have:

menu "My first menu"
config FOO
	bool "Foobar"
	help
	  First menu help
endmenu

menu "My second menu"
config FOO
	bool "barfoo"
	help
	 Second menu help
endmenu

Then the help text will be the expected one in the two menus.

gconf + qconf will be fixed later if you are OK with this one.
This is IMO a general improvement and should be finished and applied.
