Can't the history be re-written?  Would something like the following work?

1) Format the initial commit and commit it to a new repository with
matching  header information (date/time, author, etc)
2) For each formatted commit F, find the corresponding unformatted commit
U.  Determine the set of all files modified between U and U+1, and reformat
all of these files, placing them in the working copy of the new
repository.  Commit this patch to the new repository using the commit
information from U+1.
3) Delete the old repository and rename the new repository to the old
repository.

Note that variable names are outside the scope of this.
