Clarity on output

Services to be restarted:

Skipping libvirt-bin.service...

root on session services is running obsolete systemd[7946]

Since I am running a "production server", I cannot afford to blindly restart things. So I set in the configuration the default flag to be list.

Output that says Skipping however, it translates into my head as "Ignoring from checking", instead of "I am normally restarting services, but since you want list only, I am Skipping the restart of x.service..."

As a nitpick, I'd prefer some extra spaces here and there. Example outputs:

root@host:~# needrestart
Scanning processes...
Scanning candidates...
Scanning linux images...

Running kernel seems to be up-to-date.

I've changed the output to improve readability and replaced skipped by deferred:
