Ah, I missed that. Indeed it works.

What happens (eek! apply-patches.sh is hard to read) is that, if a patch
is neamd like a tarball, it is extracted in a temp dir, and that temp dir
is scanned as if it was passed as arg to apply-patches.sh:

---8<---
elif echo "$i" | grep -q -E "\.tar(\..*)?$|\.tbz2?$|\.tgz$" ; then
    unpackedarchivedir="$builddir/.patches-$(basename $i)-unpacked"
    rm -rf "$unpackedarchivedir" 2> /dev/null
    mkdir "$unpackedarchivedir"
    tar -C "$unpackedarchivedir" -xaf "${path}/$i"
    scan_patchdir "$unpackedarchivedir"
---8<---

So, yes, it works. Yet, I still find it a bit ugly (but less so than I
initially suspected). And it is not documented.

Should this be considered a feature? Can we rely on it?

If so, then I'll update the doc accordingly.

Yann E. MORIN.
