A few small changes to the "pub lish" confirmation UI.

A few small changes to the "pub lish" confirmation UI.

* Don't collapse the root directory of a directory tree, since this is usually
  going to be a very heterogeneous set of files and directories.

* Indent "(N more...)" two fewer spaces. This makes it clearer at what level
  things are collapsed when it comes immediately after a directory. E.g.

      |-- dir
      |   '-- file
      | (6 more...)
      |-- other-dir

  vs

      |-- dir
      |   '-- file
      |   (6 more...)
      |-- other-dir

I don't see a difference in your example. I think the current appearance should
be unambiguous but maybe I'm missing something. Can you show me an example? I
think I tried not indenting the elision as much but I felt it looked better
lined up with its siblings.

Update the tests and then LGTM!

https://codereview.chromium.org/11442068/diff/1/utils/pub/directory_tree.dart
File utils/pub/directory_tree.dart (right):

https://codereview.chromium.org/11442068/diff/1/utils/pub/directory_tree.dart...
utils/pub/directory_tree.dart:112: if (name == null || childNames.length <= 10)
{
The intent here is to never elide at the top level?

If so, we should add a test for this too.

https://codereview.chromium.org/11442068/diff/1/utils/pub/directory_tree.dart...
utils/pub/directory_tree.dart:126: buffer.add('| (${childNames.length - 6}
more...)\n');
You'll need to update the test too.
