This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo properties. The problematic case is when there is some commit on an unrelated branch after the last commit on the merged-from branch. When SVN records the mergeinfo property, it records the latest revision in the whole repository, which, in the problematic case, is not on the branch it is merging from. To trigger the git-svn bug, we modify t9151 to include two SVN merges, the second of which has an intervening commit. The SVN dump was generated using SVN 1.6.6 (on Debian squeeze amd64).
