Hi,

assume I have to review a package for sponsoring. Then I’d like to be
able to do
$ dget http://mentors.d.o/.../foo_1.2.3-2.dsc
$ cd foo-1.2.3-2
$ debdiff

but I cannot, because it would try to find foo_1.2.3-1.

With snapshot.debian.org, it can easily resolve this by just downloading
the source from there. At least if it was uploaded to the archive
before, but would cover most cases.

Greetings,
Joachim
