Description

Instead of resetting the function's type to the auto defined function type, it set as a user type

>>> current_function.has_user_annotations
False
>>> current_function.stack_adjustment = current_function.stack_adjustment
>>> current_function.has_user_annotations
True
>>> bv.undo()
>>> current_function.has_user_annotations
True
