helix update error

["Xavier Bestel" <xbestel aplio fr>]

Hi !

I tried to install the latest updates with helix-update. The updater didn't
download completely some rpm (short sizes), but it didn't choke and tried to
install anyway. Here it failed, telling me that there were unresolved
dependencies.
That's bad. It should behave like (or better, use) wget, and try to download
completely a package before trying to install it.
