Quite frankly, I thought the unstripped ^0 in one codepath was an
unintended quirk. What exactly do you want name-rev to give you?
$ git tag foo @^
$ git name-rev foo
So you can distinguish between annotated tags, unannotated tags, and
head-refs. Can you get it to tell you anything reliably though?
$ git tag bar @
$ git tag -a baz @
$ git name-rev @
$ git name-rev bar
$ git name-rev baz
ref, annotated, or unannotated tag? I do not think name-rev is
fundamentally different from describe: it is also only dependent on
the commit history graph. Whether I specify a revision using @, HEAD,
baz, or bar, I should get the same answer (it's just a recursive
peeler). I'm not sure what you gain by knowing the object type of the
output. If you wanted to feed something into rev-parse and get out a
commit, you'd send in $REV^0 without bothering about what it is, no?
