“make dist” works fine for me with tar 1.29:

--8<---------------cut here---------------start------------->8---
|| chmod -R a+r "guix-0.13.0.3626-da9b8"
tardir=guix-0.13.0.3626-da9b8 && ${TAR-tar} chof - "$tardir" | eval GZIP= gzip --best -c >guix-0.13.0.3626-da9b8.tar.gz
make[1]: Leaving directory '/home/ludo/src/guix'
--8<---------------cut here---------------end--------------->8---

Actually,
“guix-0.13.0.1849-cf189-dirty/gnu/packages/patches/ghc-dont-pass-linker-flags-via-response-files.patch”
is 101-character long, so without the “-dirty” prefix as above, we’re
doing OK.  :-)

Anyway, commit eef01cfe8eac8dee8ecf727e4ca459ae065e15ea augments the
‘patch-file-names’ linter to catch this issue.

There’s one problematic case left, which is t1lib, but I volunteered
Efraim to split the big CVE patch in several ones.  :-)

Thanks,
Ludo’.
