Previously, we assumed only blob objects could be missing. This patch
makes rev-list handle missing trees like missing blobs. A missing tree
will cause an error if --missing indicates an error should be caused,
and the hash is printed even if the tree is missing.
In list-objects.c we no longer print a message to stderr if a tree
object is missing (quiet_on_missing is always true). I couldn't find
any place where this would matter, or where the caller of
traverse_commit_list would need to be fixed to show the error. However,
in the future it would be trivial to make the caller show the message if
we needed to.
This is not tested very thoroughly, since we cannot create promisor
objects in tests without using an actual partial clone. t0410 has a
promise_and_delete utility function, but the is_promisor_object function
does not return 1 for objects deleted in this way. More tests will will
come in a patch that implements a filter that can be used with git
clone.
