Yeah, that's precisely what it does. I think it's good to have it like
that because when we work on the install stage it'll only have to move
everything from the "pretty-printers" directory in each submodule
instead of having to do some more complex searching. But I can leave
it in objpfx if you want.

I don't think it's a good idea to change anything in the source dir
when building. The only time I've had to do something like that is
when running a bootstrap script. If anything, the pretty printers
would have to be added to .gitignore or something.
