(I wondered also if the missing space in 5889271114a's subject line was
intentional, but it does appear in the original commit.)
Reading this patch, I'm not sure I agree that this makes the later
changes any easier. To be honest, replacing things like

Does not much help or hurt the readability, at least in my opinion. One
advantage of the pre-image is that we're doing less copying, but that's
probably splitting hairs at this point.
So, I would probably be just as happy without this patch. You mentioned
that it makes the later changes easier, but I couldn't come up with why.
I may be missing something, in which case it may be helpful to know what
that is and how it makes this change necessary.
Thanks,
Taylor
