target: create and use target_name()

Several of the sites now using target_type_name() really
ought to be using an instance-specific name.  Create a
function called target_name(), accessing the instance's
own (command) name.

Use it in several places that really should be displaying
instance-specific names.  Also in several places which
were already doing so, but which had no wrapper to call.
