renormalize histroy with smudge/clean-filter

Hello all,

I have set up clean/smudge filters to normalzize files from an application to reduce the pain when those files are tracked by git.

The clean/smudge filter work well on new commit and the result of smudge+smudge+clean is the same as the result of a simple clean, so the filter should be fine IMHO.

But whenever I do any operations which introduce not yet normalized commits, I keep getting errors.

So to get rod of those errors, I'd like to also renormalize the history:

  $ git rebase --root --strategy renormalize
  error: Your local changes to the following files would be overwritten by
  merge:
        foo/bar/baz
  Please commit your changes or stash them before you merge.
  Aborting
  $ git add foo/bar/baz
  $ git commit -m renormalize foo/bar/baz
  $ git rebase --continue
  git: 'merge-renormalize' is not a git command. See 'git --help'.
  error: could not apply abcdef... Foo Bar Baz
  [ ... ]

Huh? I never entered a command "merge-renormalize"

BTW: It does not make any difference whether I add "-c merge.renormalze=true"

What would be the proper way to renormalize history?

Any help?
