Combine refuses to copy an embedded file stream that its source holds
encrypted (opened without the password its embedded files need), rather
than write that data into another document as the file. An engine test
opens and saves such a document through the session, and the parity
entry core.attachment-only-encryption records what this covers.

attachment_add compared every attachment name, including files attached to pages as comments, so a page comment with the same file name made the reported key empty. It now compares only the document-level name-tree keys. Deleting the last document attachment when the catalog's /Names is an indirect dictionary left an empty /Names behind; it is now removed from the catalog, as the direct case already did.
