Comment (by jdemeyer):
I quite like the suggestion by Karim Belabas to use `nfsign()` together
with `nfnewprec`. I think that's a lot better than the current patch,
which is really just a hack.
Maybe you should ask Denis Simon what he thinks (perhaps with a proof-of-
concept patch)? Ideally, he fixes his script "upstream".
