That raises an interesting point for git (I don't remember seeing this
in the previous discussion, so apologies if I'm repeating). We sometimes
use SSH_ASKPASS for internal prompting, and sometimes via calling out to
ssh. So forgetting about git being consistent with the rest of the
world for a moment, I think we are inconsistent with ourselves. E.g.:

  export SSH_ASKPASS=whatever

  # this will try the terminal first, then SSH_ASKPASS, because it is
  # ssh doing the asking
  git push ssh://example.com/repo.git

  # this will try SSH_ASKPASS first, then the terminal, because git is
  # doing the asking
  git push https://example.com/repo.git

So now I'm more convinced than ever that the order should be
GIT_ASKPASS, terminal, SSH_ASKPASS.
