Thanks for the patch and the detailed explanation. The changes make sense,
so I have applied the patch.

That said looking as this part of the code as a whole, it ends up being a
bit complicated. Basically we define defaults value before the case, but
then we basically handle all cases. Then we use a for loop as a if, as
$templates contains either zero or one value.

The complexity comes from the fact this piece of code has been forked from
the non-staged one. I therefore wonder if we should try to either:
1) Simplify it.
2) make it as common as possible with the non-stage code. I believe it's
not a problem if we generate debhelper files that we don't use in
practice, as long as the stage ones are correct.

For what I understood, Samuel has committed is change in both the unstable
and experimental branches, so the changes should have been in the last
upload to experimental. That said he has done a few more changes in the
