I have code that uses this in my object-id-part15 series.  I also have
another series coming after this one that makes heavy use of it.

I believe this is because it's inline, since it is indeed used just a
few lines below its definition.  I'll drop the inline, since it's meant
to be externally visible.

This will be used when I write pack index v3, which will be in my
object-id-part15 series.

This is used in my object-id-part15 series.
