Five possibly still useful pending flag patches
This was Gna! #7613 and the five patches affecting only nations/flags might be still good (deployable) as they were, i.e., update 2*2 flags+shields spec-files and a makefile.am to get three new flags german_empire, hongkong, danzig, and the existing myanmar_old (cf. #678456) ready for prime time.
Gna! #5468 contains the SVG + 2*2 PNGs for the german_empire.
Gna! #7609 contains the SVG + 2*2 PNGs for hongkong.
Gna! #7612":https://web.archive.org/web/20170307061955/http://gna.org/patch/?7612 contains the SVG + 2*2 PNGs for danzig. JFTR, hongkong + danzig are listed in #707580 comment 7, but if they are handled here I can apparently delete that older comment.
The 2*2 myanmar_old PNGs already exist, matching an also existing invalid SVG, cf. #678456 with a visually different valid SVG. The purpose of #7613 was to test the complete procedure, not to fix invalid SVGs.
