For comparison, the ‘bzr-buildpackage’ and ‘svn-buildpackage’ tools
both construct the overlay (they call it “merge with upstream”), and
then call ‘debian/rules clean’.
I think ‘bzr-buildpackage’, at least, uses ‘dpkg-buildpackage’ and
‘dpkg-source’, which call ‘debian/rules clean’ on the resulting source
tree.

This is done so that the ‘debian/rules clean’ target can perform any
cleaning of the source tree needed before build. This ensures the
build is repeatable.

I would expect ‘git-buildpackage’ should as closely as feasible mirror
the overlay behaviour of the original ‘svn-buildpackage’, and later
‘bzr-buildpackage’ and ‘hg-buildpackage’.
That includes, AFAICT, constructing the overlaid source tree, then
calling ‘debian/rules clean’ (maybe using ‘dpkg-source’ to do it)
inside the resulting source tree, before continuing the build.
