Thanks; I think the goal of this patch is a good one.

Nice.

The description does not make it obvious to me how these two (--merge
and --keep) differ.  I think the intent of the options are:

 --keep:
	start working on a different commit, carrying over local changes
	(like "git checkout")
 --merge:
	return to <commit>, cancelling a merge-like operation that
	creates some unmerged and some clean index entries

Maybe something along these lines could be ok starting point?

	OPT_SET_INT(0, "keep", &reset_type,
		"move to <commit>, carrying over local changes in working tree",
		KEEP),
	OPT_SET_INT(0, "merge", &reset_type,
		"return to <commit>, cancelling failed merge or cherry-pick",
		MERGE),
