[libvirt] [PATCH v4 1/8] vsh: Enforce checking for missing help string
The intention is to move vshCmddefCheckInternals out of vshCmddefOptParse to
our test suite. First step to do that is to enforce checking for an existing
help string (that also means it's non-empty) in a command because a command
without a help is not much of a use.
