I noticed that at-bottom is used instead of better below-selected
for some completion-at-point commands.  For example,
completing a color in the Customization UI displays the
*Completions* at the bottom even when there is no active minibuffer.

Since completion-at-point commands set the value of `this-command'
I wonder wouldn't it be right to check its value?
