git suddenly started putting up a dialog instead of asking for my password on the command line

[Joel Rees]

I decided to try to ssh into the osdn.net shell server, and it gives
me the same (modal) popup dialog.

So I'm suspecting ssh-agent, but trying ssh config, and it claims I
already have the config file open.

Ubuntu was claiming my vi was nano (pain in the backside!), and I
tried to fix that, but now it seems that Ubuntu is claiming my vim is
not installed, but

    vi --version

says vi is vim.

I think this is a clear case of too many cooks spoiling the soup.
