bug#12193: 24.1.50; 24.1.50; Completion broken in revno 109116

[chad]

1. Run `emacs -Q'.
2. Type: `C-x 1' (make sure there is only one window)
3. Type: `C-x C-f /tm TAB'
4. Emacs creates a new window for the completions, but puts the cursor
   in the wrong window (it's back in the original window, not
   *Completions* or the minibuffer.

If the windows are already split for any reason, this bug isn't triggered.
