I'm using b4 now

[Palmer Dabbelt]

I figured if we're changing workflows to include patchwork, I might as 
well get with the flow and start using b4 as well.  It's super nice like 
everyone says it is.  I think I've got it working to the point where it's 
better than my old flow already so I'm going to run with it, but there 
might be some rough edges for a little while.

I've kind of just picked some arbitrary settings and it's in the middle 
of a mess of scripts, so if anyone sees anything weird then just point 
it out as it's likely just a mistake on my end.
