You can use .git/hooks/pre-commit hook in the repository the editor that munges line-termination, to fix things up.

The hook is called with GIT_INDEX_FILE set to the appropriate index file, so you could "git-diff-index --cached --name-only HEAD" to obtain the list of files being committed, sanitize the working tree files and update-index them again before returning true from the hook.

This is a silly example to standardize on uppercase.

        git-diff-index --cached --name-only HEAD |
        xargs sh -c '
                while case "$#" in 0) break ;; esac
                do
                        perl -p -i -e "\$_ = uc(\$_)" "$1"
                        git-update-index "$1"
                        shift
                done
        ' dummy
        exit 0
