This one is a bit hairy, because two things might happen if the picture has a geo location: - A dive gets a newly generated dive site set. - The dive site of a dive is edited. Therefore the undo command has to store keep track of that. Oh my. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
