Hi, 

When I try to access ftp through ido I am getting on 24.1.50.1

How to reproduce:

M-x ido-mode

C-x f /ftp:anonymous <at> cran.r-project.org:

This doesn't happen with emacs 23. It also works fine without IDO on
emacs 24.

Any ideas?


Vitalie.

There was a subtle change in completion of remote files. As long as you
type the remote host identification, it doesn't complete for that host
if there isn't an established connection yet. The reason is, that people
felt disturbed by error messages or password requests, even when they
have mistyped something and didn't want to connect yet.

When you start to type a local file name of that remote host (start with
"/"), completion shall work as expected in ido.

I believe the behaviour is correct now, after that change. I'm closing
the bug. Feel free to to continue discussion, if you believe it doesn't
work correctly.
