Since you're poking around interactive rebase, this is my own poke around the rebase code. Started last year, quickly rebased, may contain hazardous material, YMMV.

I reverted it to the original approach, since annotated commits seem overkill to me and I think its better to reflect the actual files on disk without having some voodoo magic inbetween. I left the string accessors with name instead of ref in their names, since its a name (char *) and not an actual git_reference object.

So the interface looks like this again:

const char *git_rebase_orig_head_name(git_rebase *rebase);
const git_oid *git_rebase_orig_head_id(git_rebase *rebase);
const char *git_rebase_onto_name(git_rebase *rebase);
const git_oid *git_rebase_onto_id(git_rebase *rebase);

LGTM. Thanks @eaigner!
