Trivial virsh.pod additions --all for "list" command and similar
This is just a trivial patch to virsh.pod (from git master). It adds the
following pieces to the virsh man page:
+ Shows the --inactive and --all optional parameters for the list
command.
Closes Bugzilla #575512, reported by Renich Bon Ciric
https://bugzilla.redhat.com/show_bug.cgi?id=575512
+ Corrects the existing description of the list command, to now say
that only running domains are listed if no domains are specified.
The man page up until this point has said all domains are listed if
no domains are specified, which is incorrect.
+ Adds the "shut off" state to the list of states for the list
command.
+ Adds a missing =back around line 755, that pod2man was complaining
was missing.
