- Restore the office-docx new-document example from master. #6040 concerns
edits, and no Word creation case covers its removal.
- Tell direct package writers to copy each member once into a new ZIP;
python-docx, python-pptx, and openpyxl all reopen packages with duplicate
members without error.
- Anchor the script-name assertion so hyphenated names such as edit-docx.py,
which shadow no module, do not fail the Word e2e.
