Bug#814686: Acknowledgement (uscan, uupdate: vesion=4 and --destdir)

[Osamu Aoki]

Hi,

For multi-tarball-package situation, I introduced -f syntax to work with
it without passing many file names.

So adding --destdir support to uupdate is one way and let the uupdate
copy files from $destdir to ...

But I realized to add copy code within uscan is simpler overall.

So whenever script is called in version4, it gurantees to have properly
renamed and repackaged tarballs in ../   destdir always contain original
downloaded files as in version3 .
