Apart from this I have reviewed the patch and found it a faithful
conversion.

I am not an expert in the diff area  and wonder how
the cmd_diff_files functionality is achieved with just a stat call
and then comparing it to  ce_match_stat. 'Using "dirty" ignores
all changes to the work tree of submodules, only changes to the
commits stored in the superproject are shown.' So I'd have
expected ce->oid to be compared (is there an index entry differing,
i.e. more than one stage?)

Cool.
