[NTG-context] Multi-par footnotes. Indent second and later paragraphs?

I have a few footnotes that are longer. New paragraphs are not indented, I’d like to have everything except the first paragraph indented. By hand is OK, but the only thing I can think of is a couple of ~ at the start of each new par, not very nice and it doesn’t by definition align perfectly. Is there a nicer way? G
