The graph traversal code here passes along a name_path to build up the pathname at which we find each blob. But we never actually do anything with the resulting names, making it a waste of code and memory.
This usage came in aa1dbc9 (Update http-push functionality, 2006-03-07), and originally the result was passed to "add_object" (which stored it, but didn't really use it, either). But we stopped using that function in 1f1e895 (Add "named object array" concept, 2006-06-19) in favor of storing just the objects themselves.
Moreover, the generation of the name in process_tree() is buggy. It sticks "name" onto the end of the name_path linked list, and then passes it down again as it recurses (instead of "entry.path"). So it's a good thing this was unused, as the resulting path for "a/b/c/d" would end up as "a/a/a/a".
