### Please describe the problem.

There was some recent work to ["centralize" such prompts](https://git-annex.branchable.com/devblog/day_457__improved_ssh_password_prompting/) but it seems some are still "leaking through" multiple times.  May be it is because there are 2 available repos on that remote host, so annex generates one per each of those? (although it knows only about origin)

### What version of git-annex are you using? On what operating system?

6.20170810+gitgff6f9e203-1~ndall+1

### Please provide any additional information below.
