- Added space char for better copy+paste

[guettli]

"Disconnecting from user@host .... ".

Before simple click on the user@host contained the three dots.

I added one whitespace character. The build failure of Travis says something about "deepcopy()".

Unfortunately I could not find a way to restart the travis test.

Please have a look at the patch. It is the most simple patch I ever created, but it helps
daily working with fabric.
