Yes, this looks right.
It'd be nice to be able to apply the patch locally so I could also
look at the --color-words version, but it's not a real big deal.
In general, this is how the index stuff works in merge-recursive:
* In unpack_trees_start(), we call unpack_trees() using the_index as
src, and tmp_index as dest.
* As soon as unpack_trees() finishes, we swap: (orig_index,
the_index) = (the_index, tmp_index).
* We ONLY use orig_index (also called unpack_opts.src_index) in the
was_*() family of functions, which query about what the index was like
before the merge started. (To name these functions explicitly:
was_tracked_and_matches(), was_tracked(), and was_dirty()). ALL other
callsites within merge-recursive.c should be operating on the_index,
or, after your patch, o->repo->index.
(Also, if you want to avoid merge conflicts, you might want to avoid
unrelated changes like the whitespace and alignment fixes. You'll be
happy to know, though, that I think I fixed them all up as part of the
en/merge-recursive-cleanup series in pu.)
