Ok.

Makes sense, the "popon" directory has no version number.

I'll try this out, but in the future it would be useful to see the
contents of the variable `package-alist'.  This is all related to that

That means that all packages have /been/ updated.  I also just noticed,
that it is printed out unconditionally, even if no VC packages have been
updated (because non are installed).
