0.85 from Git, with bonus feature: it works

I failed to adequately test v0.85.1 install from outside the git repo; make(1) would complain of missing source to make the script as distributed.

Fixed, and tested that install works from tarball, as I should have done for the .1 release.

However : there are other changes in this repository since then, changing functionality, and in a rush I forgot that and so this should not have been tagged as a release.

So: 0.85 was SVN; 0.85.1 was Git but broken. 0.85.2 is Git and working, but with other functionality not matching 0.85. This is just repeated fail on my part. Giving up on 0.85.x and will just cut 0.86.
