OK putting idiff stuff in rev_info is probably the right choice. But
we all three fields prefixed with idiff_, maybe you could just add a
new struct "idiff_options" to contain them and add a pointer to that
struct in rev_info. Then "opt->idiff" is enough to know if idiff is
requested instead of relying on idiff_oid1 (seems too random).
