A dump no longer embeds a picture or a PDF that is on disk: Restore reads it from there, as a clean file's text is

Every Dump carried each image's and PDF's bytes in base64 (a 900 KB PDF
made a 1.3 MB dump), and a Restore showed that copy however the file had
changed. One on disk now goes by its path alone; one not on disk (no
file behind it) still has its bytes kept.
