Zbigniew Jędrzejewski-Szmek 20b3f379cf systemctl: allow multiple arguments to --type
This mirrors --property, and is generally useful.

New functionality is used in bash completion.

In case of zsh completion, new functionality is less useful
because of caching. Nevertheless, zsh completion for restart
is made to behave more-or-less the same as bash completion.
At least sockets can be restarted.
