I have thought that if there exist stage #0 in index, git simply _ignores_
higher stages, so git-add simply adds stage #0 and does not delete higher
stages.

But I see that "git update-index --unresolve" (and its predecessor 
"git-unresolve") simply recreate stages #2 and #3.


The documentation of "git update-index --unresolve" lacks this info,
and it doesn't tell one what it is for (see commit message for commit
ec16779 (Add git-unresolve <paths>..., 2006-04-19)).
