That's odd. Make sure you remove "finder-inf.el{,c}" and re-make. Its
format has changed and it needs to be re-generated.

Good point. The raw vectors should be replaced with calls to
`package-desc-create' with the appropriate arguments.

My rationale behind that was to have the multi-file package be in
"source form": all the files in the repo would be actual user-created
source files, and not generated files of any kind. That is probably
not necessary for testing, so the multi-file package directory could
be replaced with a single .tar. This means that all of the
package-building functions (and parts of `with-package-test') could be
removed as well.
