You don't know that the user has pressed TAB. There are contexts where 
the user hasn't pressed TAB, but we still call 
file-name-all-completions, e.g. in an idle timer callback, to show what 
*would* happen *if* they press tab.

Sure. I'm the author of this report. Still, it would be nice to have 
`non-essential' have the intended effect.
