+REBASE VS. PULL
+---------------
+
+Originally, git-svn recommended that the remotes/git-svn branch be
+pulled from.  This is because the author favored 'git-svn commit B'
+to commit a single head rather than the 'git-svn commit A..B' notation
+to commit multiple commits.
+
+If you use 'git-svn commit A..B' to commit several diffs and you do not
+have the latest remotes/git-svn merged into my-branch, you should use
+'git rebase' to update your work branch instead of 'git pull'.  'pull'
+can cause non-linear history to be flattened when committing into SVN,
+which can lead to merge commits reversing previous commits in SVN.
