Paul, you did find a regression in the changes of 2/4.
I did not expect the script would actually catch such a bug.
The "sorting out" in 2/4 caused autodate.sh to see temporary
untracked files from concurrent conversions of figures.
I'm sending a followup patch (5/4) partially reverting 2/4.
I should have run the test under a newly cloned Git repository...
Thanks, Akira
