bug#26993: 25.2; package.el: docstrings keep pointing to old code after package upgrade

[Heikki Lehvaslaiho]

There is a long standing problem that keeps docstrings pointing to the old location after the package has been upgraded.

See https://emacs.stackexchange.com/questions/12158/docstrings-are-invalid-after-upgrading-packages

Emacs restart or manual load-library on the new new file do fix the problem, but shouldn't loading happen automatically at package upgrade?

I could not find a previously submitted bug, nor is the paradox package trying to handle this problem. I mostly upgrade using the function paradox-upgrade-packages.
