Oh, I see what you mean now. IMO it would be a mistake to attempt to do this in such a way that it upgraded only the m4 files and not the C files. Changes made to gnulib modules (which typically consist of some m4, some C, and some metadata) often touch both m4 and C at once; it seems unwise to try to arbitrarily split those up. -- Colin Watson (he/him) [cjwat...@debian.org]
