dired path and ido

[John Russell]

I actually saw two separate bugs while verifying a fix that was sent to
me.  

1) The first is that when using ido-mode for find-file, dired does not
open when you select a directory.  I can't seem to find any way to open
dired from find-file which I always found very useful.  Note that this
is only in ido-mode and works fine with the standard find-file.

2) When I hit enter on '..' in dired to go up a directory, everything
works fine unless you go up into '/' (root directory).  At this point
everything _looks_ fine, but when you then descend into a directory
again, the path now looks like so:

/:/bin:

instead of so:

/bin:

Its almost as if the /: gets stuck at the beginning. This only happens
when you get to / and then go back down.
The only thing I've found that this messes up is the new external viewer
command mapped to 'v' but I'm sure there are others I haven't found.
