Clearly the format 2.0 has been implemented as an academic exercise
because we're speaking of wig&pen since so long... but it's not the format
that I want to push for wide adoption.

Well, the man page is clear: you have to call dpkg-source -b on a
directory with all the patches _applied_. That's the default state after
unpacking a 3.0 (quilt) source package. And when you do that, you don't
get this patch that reverts everything.

So if you want to try out the new source format, you have to adapt to
this. It might mean that svn-buildpackage needs change, I haven't thought
about it yet.

Maybe you can work around this for now by making sure that "debian/rules clean"
gives you a patched tree.

It's not troublesome at all. You get a sensible behaviour without using
quilt when doing: unpack, change, build. (Provided that you unpack a
source package using the new format already...)

The only change that you have to do concerns quilt using packages and is
to apply patches the first time before calling dpkg-source -b. It's not
much work.

You don't have to use debian/patches/ if you don't want too. And what the
Format: 2.0 can do can also be done by the format "3.0 (quilt)".
