otherwise a removed file would be recreated

+ use "git log" again to get weekly commit logs
+ use "git rev-list" only with --rev-list option; useful to list differences
  between branches

http://lists.freedesktop.org/archives/libreoffice/2011-April/010408.html

use "git rev-list --pretty=medium" instead of "git log"
to be able to use origin/libreoffice-3-4 ^origin/libreoffice-3-3
to generate list of changes that are in 3.4 but not in 3.3

FIXME: we should find another way to tell dowload the right version
of used sources

based on libreoffice/build/bin/lo-pack-sources; still need some clean up

The --with-distro options might come from bin/build-ooo in a "build"
style build, and in that case, the relevant configure options are
already on the command line, too.
