Well, the thing is, I don’t know how to convert my downstream project, which 
has 10 years worth of its own development and regular merges against two 
version of the git mirrors, the later one quite official and GNU/FSF sanctioned.

I might cut off all history prior to 2005, “flatten” the merges somehow (so 
that they lose their Emacs-side parent), and then re-connect to the new Emacs 
repository with a merge right at the point where you do the conversion.

This will destroy a lot of history on my end, which is lamentable.

I’d say, do not create this alignment table if it is a lot of work.

OK, with that I could go find a machine.  However, I probably couldn’t do this 
every time I start reposurgeon.

Maybe I can figure out how to do this cutting operation manually with git.
