It works!  Now I don't see either the manufactured commits or the
patched-in deletions.

I had not previously bothered to patch the places where a file was added
on the branch immediately after being added on the main, but now it
seems worth doing.  That will get us down to a *very* small number of
manufactured commits in the final version.
