I intend to orphan the popup-el package.

This package is no longer loaded by my init.el and it would be better if
someone who actually uses the package maintains it.  There is nothing
wrong with it; no need for an RM or anything.

This is a team-maintained package, so the adoptor should either replace
me in Uploaders:, or alternatively take the package out of the team's
hands.

The package description is:
 popup.el is a visual popup user interface library for Emacs. It
 provides common UI widgets such as popup tooltips and popup menus.
