show_object(): push path_name() call further down
In particular, pushing the "path_name()" call _into_ the show() function would seem to allow - more clarity into who "owns" the name (ie now when we free the name in the show_object callback, it's because we generated it ourselves by calling path_name()) - not calling path_name() at all, either because we don't care about the name in the first place, or because we are actually happy walking the linked list of "struct name_path *" and the last component. Now, I didn't do that latter optimization, because it would require some more coding, but especially looking at "builtin-pack-objects.c", we really don't even want the whole pathname, we really would be better off with the list of path components. Why? We use that name for two things: - add_preferred_base_object(), which actually _wants_ to traverse the path, and now does it by looking for '/' characters! - for 'name_hash()', which only cares about the last 16 characters of a name, so again, generating the full name seems to be just unnecessary work. Anyway, so I didn't look any closer at those things, but it did convince me that the "show_object()" calling convention was crazy, and we're actually better off doing _less_ in list-objects.c, and giving people access to the internal data structures so that they can decide whether they want to generate a path-name or not. This patch does that, and then for people who did use the name (even if they might do something more clever in the future), it just does the straightforward "name = path_name(path, component); .. free(name);" thing.
