I think the reason you needed to do this was because you wanted to move delete_refs() to the common code. It is true that delete_ref() can be moved to the common code. And most of the code in delete_refs() is just a loop calling delete_ref(). But delete_refs() also does the very files-specific optimization of calling repack_without_refs() before the loop. *That* call shouldn't be in the common code.

So my suggestion is that you write a common_delete_refs() function that only includes the loop over delete_ref(), and a files_delete_refs() function that is basically

    {
            result = repack_without_refs(refnames, &err);
            if (result) {
                    ...report error...
                    return result;
            }
            return common_delete_refs(...);
    }
