boolean isProtectedParameterOffset(int stackOffset) {
		return isParameterOffset(stackOffset) && !function.hasCustomVariableStorage();
	}
Determine if the specified stackOffset corresponds to a parameter which should not be 
modified via the stack editor other than its name and comment.  This is neccessary when
(i.e., custom storage is disabled) in which case the function signature should be adjusted
using the Function Editor.

@param stackOffset stack frame offset
@return true if the specified stackOffset corresponds to a protected parameter with 
an auto storage assignment.
