Christ. When you start doing octopus merges, you don't do it by half
measures, do you?

I just pulled the sound updates from Takashi, and as a result got your
merge commit 2cde51fbd0f3. That one has 66 parents.

That kind of merge either needs to be split up, or gitk needs to be
made better about visualizing it, because it ends up being *so* wide
that the history is hard to read.

I think you'll find that having that many parents also breaks old
versions of git.

Anyway, I'd suggest you try to limit octopus merges to ~15 parents or
less to make the visualization tools not go crazy.  Maybe aim for just
10 or so in most cases.

It's pulled, and it's fine, but there's clearly a balance between
"octopus merges are fine" and "Christ, that's not an octopus, that's a
Cthulhu merge".
