An insufficient or ancient Obsoletes tag has been discovered in the
package. It should either be corrected or dropped.

The tag is superfluous, because it doesn't obsolete a package found in
Fedora 16 and newer, and that package is ancient:

    git-0:1.7.7-2.fc16.i686  is oldest
    git <= 0:1.5.4.3  obsoleted by  git-all-0:1.8.3.1-3.fc20.noarch
