I'm not sure why we would move the stuff in Documentation/misc to an
external repo. It looks like we used to generate .html files from the text
files that are in there. It's a few fixes to Documentation/misc/GNUmakefile
to get that working again. Can we put the generated .html files somewhere
on the new website, make sure we link to them, and be done with it? Once
that's working, the remaining announces and changes from the old website
would just need to be dropped into Documentation/misc, i.e., update
anything that is missing.
