Ah, OK. Carry on, then. ;)

I'm 99% sure it would indeed go away, since the patch I showed earlier (to make the parsing more lenient) worked. But if you want to try, I suspect you could do it with git-filter-repo's --commit-callback option. Or if you don't mind being a little loose with the parsing, probably just piping fast-export through sed, and then back to fast-import.
