ls command has changed behaviour on trailing slashes

[zignig]

used to work

 ipfs ls Qmdj5VVRUvhenQLYh4gDFSm5GYK88D6vJxhEUZNM8ehLwb/boot
Error: invalid ipfs ref path

however it works with the /ipfs/ at the front..

ipfs ls /ipfs/Qmdj5VVRUvhenQLYh4gDFSm5GYK88D6vJxhEUZNM8ehLwb/boot
QmU5NG6Dnxkk6TwraH7VwVvzwjGWXsoTMvLjUsrsLk8zkL 175356987 coreos/
QmYvY2sg4SCSLKC3fc9Q2vN4cUEB4LzBux5eHfRYvk4KPx 906       debian/

if you add another level it does work...

ipfs ls Qmdj5VVRUvhenQLYh4gDFSm5GYK88D6vJxhEUZNM8ehLwb/boot/coreos

There seems to be a change in counting the slashes in a ipfs path.
