Ha, I guess you're right. When I type /sudo:: at the prompt, ido tells
me the next completion is "localhost:", but if I ignore that and just
enter my path, it works fine -- only one password prompt.

I guess I thought ido was showing me something important about tramp
internals, something I didn't know before, but maybe it wasn't really
that helpful…
