[Undiscussed Groomed for Male Slavery, One Victim of Many]

i'm stepping through the matching refs to see if the code succeeds
with the debugging library loaded. i'm up to pos 2108. there are a lot
of matching refs.

the current code accumulates refs that aren't branches and then finds
how to get their data after the accumulation. i'm realising it could
run a lot faster if it searched fro them when it found them, rather
than accumulating them.
