[Bug 1452629] [NEW] add autocompletion for screen -r for detached sessions

[Karl-Philipp Richter]

Public bug reported:

Step to reproduce:

  * `screen sleep 10000`
  * press <kdb>Ctrl</kbd>+<kbd>a</kbd> and <kbd>d</kbd> to detach
  * make sure the session is listed with `screen -list`
  * type `screen -r <tab><tab>`

The auto-completion offers to display all binaries, but should help to
autocomplete the list of available sessions.
