blame -L questions

Junio,

I'd like git blame to be able to emit multiple blocks when using it
with -L /start/,/end/.

My use case is emitting blocks that are wrapped in

#if defined(WHATEVER)
....
#endif

I was going to use the syntax -L /start/../end/ for this.

I naively thought I might just be able to setup multiple blame_entry's
linked through the next/prev pointers at the start, but that clearly
does not work.

So I was wondering if you could give me any tips about how the
scoreboard, blame_entry, and origin all fit together before I injure
myself. :-)

Thanks,

j.
