Also would be nice to use format-patch -C for things like patch 2/4 in the future, as that'd make reviewing easier imo.

Thanks for the review. -Daniel

That way the control flow is clearer, and it prepares the stage to extract these ums functions and hide them somewhere. There's still tons of display stuff outside of these, but that requires more work.
