I briefly wondered if we have some callsites that do not want
o->found_changes to be modified (hence pointing this field at
elsewhere), but the fact that you can _remove_ this field means that
there is no such use case, which is good.

Is there a good reason to move the assignment up? "The fact that
this function was called even once means we found some change" is
probably a good argument, but then I'd prefer to have a blank before
it to separate it (the first statement) from the block of decls.
No need to resend. Thanks.
