incomplete tuplets

[David Zelinsky]

Recently there was a discussion on the Music Engraving Tips facebook
group involving a non-dyadic time signature, that required notating a
*pair* of quintuplet 16th notes, without the rest of the quintuplet.
It's not that there were rests for the other three.  The measure just
ended after the first two.

The suggested notation for this was to use a quintuplet bracket that was
open on the right, and extended slightly beyond the second notehead, or
beyond the beam.  See attached.

Is there a sensible way to do that in Lilypond?  I've searched around in
the documentation but haven't found anything.

I don't want to debate the merits of this notation--I have my own doubts
about it.  I'm just curious how to do such a thing in Lilypond.
