- Update to version 4.2.0:
  + See
    https://github.com/vermaseren/form/wiki/Release-Notes---Form-4.2.0
    for list of changes.
- Drop form-devref-pdf.patch; incorporated upstream.
- Add BuildRequires on git, required to ascertain revision id.

- Initial package.
- Add form-devref-pdf.patch to fix a typo preventing devref PDF
  documentation from generating.
