You can also do:

git filter-branch --commit-filter '

                git commit-tree "$@";
        else
                git commit-tree "$@";
        fi' HEAD

Note, if you are using this command in the Windows command prompt, then you need to use " instead of ':

git filter-branch --commit-filter "
        if [ "$GIT_COMMITTER_NAME" = "" ];
        then
                GIT_COMMITTER_NAME="";
                GIT_AUTHOR_NAME="";
                GIT_COMMITTER_EMAIL="";
                GIT_AUTHOR_EMAIL="";
                git commit-tree "$@";
        else
                git commit-tree "$@";
        fi" HEAD
