This feature is from prehistoric times. It was already in the revision 1.1.

I guess that's because the name displayed in the mode line should be the
same as provided in the completion for consistency.

Maybe we should add an explanation text to the completion candidate like
e.g. `* (all nodes)'. And accept also `*' but don't display it in the
completion list.

Yes, this looks like wildcards.

Displaying something like `all nodes' in the mode line would inform about
what has happened, but I have no idea how it could inform how to get back.
