+ * "git pull --rebase" always chose to do the bog-standard flattening
+   rebase.  You can tell it to run "rebase --preserve-merges" by

+ * "git push --no-thin" actually disables the "thin pack transfer"

  * Magic pathspecs like ":(icase)makefile" that matches both
    Makefile and makefile can be used in more places.

+   when rebasing, there should not be a need for merge summary.
