Ido and hosts named with a single letter.

[Michaël Cadilhac]

Try this :
emacs -Q
M-x ido-mode
C-x C-f /tmp

Everything's okey.
Now, do the same but before, add a line with a `w' in your known hosts:
echo w >> ~/.ssh/known_hosts

It will result in the error « Login failed ». Disgracious.

I propose the following patch, which makes ido allow such host names.
