s/040000/160000/ I would think (if you really meant to expose a
tree, write it as 40000 instead, so that people will not get a wrong
impression and reimplement a broken tree object encoding some popular
Git hosting site broke their customer projects with ;-).
I am not sure $treeish^{resolve} is a great syntax, but I like the
concept and agree that it is a lot more sensible to handle this at
the level of sha1_name.c layer than an ad-hoc solution in the
cat-file layer.
