There are more arguments than 'shutdown --mode' that accept a
list of strings separated by commas. 'nodedev-list --cap' is one
of them. To avoid duplicating code, let's separate interesting
bits of virshDomainShutdownModeCompleter() into a function that
can then be reused.

^This sounds rather sub-optimal. I wouldn't even insist on making the
suggestions contextual like it is now, IOW not suggesting options which have
already been specified and would rather return the same list of possible
options than a string with the user input prepended.
So IIUC, for 'shutdown --mode <TAB><TAB>' you want to see:
"acpi", "agent", "initctl", "signal", "paravirt"
and for 'shutdown --mode acpi,agent,<TAB><TAB>' you want to see the same
list again (optionally with already specified strings removed)? Yep,
that would be great but I don't think that is how readline works. At
least, I don't know how to achieve that. Do you perhaps have an idea?
