Flared hairpin across line break

[Andrew Bernard]

I'd like to have flared hairpins that only flare at the terminating end after a line break.

The following example shows that using the flared hairpin stencil in a simple minded way causes it to flare at the first break, which I want to not have.

Is there some magic that can be done with alter-broken?
