Gotcha!  Replying to both messages here.

I wanted to see what it does with empty `package-vc-selected-packages'.

Yeah, I know.  A strange "first thing one does".  :)

So good!  The documentation before said that it refreshes the given
package.  Hence, I kept scratching my head.  Now, it all makes sense.

As for the name, how about rebuild?  All those steps normally happen
during a build process.  I think "refresh" sounds much too close to
"update".

Early or late, we need to show at least the traditional Emacs type
predicate error.  I say that because it took me ten minutes to find the
problem. :)

Oops, I since then restored everything back.

No worries though, I will do more testing going forward!

I see.  Smart!

Definitely!

I think that would make sense.

So much for "scratch" branches. :-/
