I meant the confusion is abnormal messages from the output of "git filter-branch -- --all". For example, this is an output of "git filter-branch -- --all": Rewrite bcdbd016c77df3d5641a3cf820b2ed46ba7bf3b4 (5/5) (0 seconds passed, remaining 0 predicted) WARNING: Ref 'refs/heads/master' is unchanged WARNING: Ref 'refs/heads/no-newline' is unchanged WARNING: Ref 'refs/heads/original' is unchanged error: object 1bf53b49c26465454e4ac377f2ed3f91bb1d6ac1 is a tree, not a commit error: object 1bf53b49c26465454e4ac377f2ed3f91bb1d6ac1 is a tree, not a commit fatal: ambiguous argument 'refs/replace/8a2016f3730cad8309c110f819c855403ed0a5b9^0': unknown revision or path not in the working tree.

Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' WARNING: Ref 'refs/tags/treetag' is unchanged You can see a lot of terrible messages such as "error" and "fatal". But on the whole, the result of "git filter-branch -- --all" is not so abnormal. So, this is a just problem about abonormal messages. I think this messages should be suppressed. How do you feel about it?
