There's a catch here with the backport packages. When the
update-from-*-master script is run, it syncs the changelog of the
backport tree with the master tree and adds the
"~<target-series>.<build-number>" prefix to the current version number.
That means we end up losing the previous  backported versions on the
changelog. So when using the output from rmadision with backport
packages, dpkg-genchanges will add more entries than we really want.

The fix would be to remove everything that comes after "~" with
something like:

srcpkg_debopts="-v${updates_version%~*}"
