Thank you, that's a good catch.

The problem is in IHelp using RiDriver carelessly --
RiDriver#initialize uses ARGV for its options.

Subclassed it to redefine #initialize to take the
options as a parameter. (And added ARGV to test unit setup.)

Could you try the following and see if it works better now?
