Define NFD_PORTAL_AUTO_APPEND_FILE_EXTENSION to 0 if you don't want the file extension to be
appended when missing. Linux programs usually doesn't append the file extension, but for consistency
with other OSes we append it by default.
Define NFD_APPEND_EXTENSION if you want the file extension to be appended when missing. Linux
programs usually don't append the file extension, but for consistency with other OSes you might want
to append it. However, when using portals, the file overwrite prompt and the Flatpak sandbox won't
know that we appended an extension, so they will not check or whitelist the correct file. Enabling
NFD_APPEND_EXTENSION is not recommended for portals.
