My fault.

I think I did consider this but I don't remember why I didn't go down
that route. It could be I didn't like the slightly more complex way of
toggling virtual buffers. I am a bit short of time at the moment but I
have put this in my TODO and will look at it again.

Meanwhile feel free to change the patch.

    Turn on virtual buffers automatically when no matches
