Quilt patch for patching things in the debian folder

[Thomas Goirand <zigo@debian.org>]

Hi,

I've just seen an (ugly) instance of many quilt patches in
debian/patches that are patching things inside the debian/ folder. I am
wondering if it would be wise to forbid this entirely, and write about
it in the policy (maybe it is there already?). There's no sane reason
why this would happen: our package_<version>.debian.tar.gz should come
patched already, and shouldn't need any quilt patch.

Thoughts anyone? Is there reasons why this would be a valid way to do
things?

Thomas
