Hmm, should the root portions change the umask before creating any
files?  (I think, it's no good idea.)

My debian/rules contain

        chmod -R u=rwX,go=rX debian
        chown -R root.root debian

BTW, if the files already exist, the mode shouldn't get changed, does
it?  (What happens if you touch debian/files debian/substvars and chmod
'em rw-r--r--?)
