I came up with the script below, which you can use like:

  ./script v1.8.2.3 git-1.8.2.3.tar.gz

It expects the tag to already be pushed up to GitHub.  I'll leave
sticking it on the "todo" branch and integrating it into RelUpload to
you. This can also be used to backfill the old releases (though I looked
on k.org and it seems to have only partial coverage).

It sets the "prerelease" flag for -rc releases, but I did not otherwise
fill in any fields, including the summary and description. GitHub seems
to display reasonably if they are not set.
