I replied on the final commit as I didn't review this mail before it was committed.

The patch adds a console prompt to a library, which we should never do. We designed our entire authentication library to use prompt handlers and we should/must use such handlers here as well.

Our library should /never/ directly communicate to the user without allowing a library user to at least override this behavior. But in almost every case the library user (=subversion client application/integration) should just provide a prompt implementation.

I see this as a 1.6 blocking issue, for the reasons mentioned above.
