Yeah, I already see me typing s<return>finish<return> gazillion of times when
trying to step into a function call that produces a function argument
... there is
already the very very very annoying tree_code_length function that you get for
each TREE_OPERAND (...) macro on function arguments. I'd be very opposed
to any change that makes this situation worse.
