I don't think Emacs calls ssh-askpass directly -- it just leaves all
that stuff up to the OS setup, I think?

In any case, I was unable to reproduce this on Debian, presumably
because there's a lot of passphrase caching going on.  Without it I'm
just getting:

Running "git push"...
git@github.com: Permission denied (publickey).^M
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

So do you have a more complete recipe for how to reproduce this bug?
