考虑以下布局：
git | svn ----------------------------------- master | trunk local_experimental | experimental
以下命令列表是否合理：
git checkout local_experimental
#hack hack hack
#commit changes to experimental svn branch
git svn dcommit experimental
#update the git repository from svn
git checkout master
git svn rebase
git checkout local_experimental
#how will svn handle the two following commands?
#rebase the experimental branch on master to get newest changes
git rebase master
git svn dcommit
