       dh_dpatch_unpatch simply calls dpatchdeapply-all.  All patches listed in debian/patched are then
       unapplied in the current directory. The command does not fail if the patches have already been unapplied.

       dh_dpatch_unpatch is usually called indirectly in a rules file via the dh command.

               %:
                       dh --with dpatch $@

       It can also be direcly called in the clean rule.

               clean:
                       dh_testdir
                       dh_testroot
                       [ ! -f Makefile ] || $(MAKE) clean
                       dh_dpatch_unpatch
                       dh_clean
