마누엘 1f09aed834 interactive: explicitly fflush stdout before expecting input ...

At least one interactive command writes a prompt to `stdout` and then
reads user input on `stdin`: `git clean --interactive`. If the prompt is
left in the buffer, the user will not realize the program is waiting for
their input.

So let's just flush `stdout` before reading the user's input.
