So this all seems good to me and makes sense to get in for 4.10. Should I

Hard would it be to bash out a little tool that could break those long
lines? It seems like the format should be able to support that? I'm no
XML expert, but a quick experiment breaking the long lines in
fieldseq_bt.svg didn't create any problems; white space is white space.
Indeed, given the small number of images and the infrequency with which
they change, perhaps that could just be done by hand?
(In the process I learned that if you visit an SVG image in emacs, it
actually renders and displays the image!)
