Comment (by embray):
Even easier is to modify `sage-spkg` so it still handles the prompting
(otherwise a lot of package parsing stuff needs to be duplicated), but for
`./sage -i` first have it run `sage-spkg -d` (download-only) which is the
only context in which those prompts are displayed, then run `make` (which
in turn calls `sage-spkg`) but with the package already downloaded, it
won't prompt. I might add some options to `sage-spkg` to make extra sure
it doesn't prompt.
