Thanks for taking the time to write this explanation. The file ‘v.c’ is1.2MB though, and it’s definitely not the preferred form for edition.
What’s the 15KB above referring to? I’d welcome a patch to adjust thecomment, unless I’m missing something. :-)
It would be great if you could bring up this issue with upstream,perhaps mentioning https://bootstrappable.org/.
Thanks, and sorry for the long delay!
Ludo’.
