Describe the issue

When SSH is used as transport, the ssh program is using SSH_ASKPASS to get the password to unlock a private key if it is set.

The programs typically in use there, if they are UI-based, may also auto-fill the password without bothering the user.
While we unconditionally override it this workflow is disturbed.

How to reproduce

No response

Expected behavior

When SSH_ASKPASS is set, the programs the user decided on should still be respected. However, this might not always work as it should if these programs expect a terminal environment, so solving this may be more involved.
