tests/test-narrow-widen-no-ellipsis.t

tests: show that adding an already included path still calls narrow_widen()

This patch adds tests demonstrating that we still go to the server in
non-ellipses widening when we have that path already on the client and there is
nothing new to download.

The next patch will try to make client side logic smart and not go to the server
if we don't need to download anything.

Widening preserves parent of local commit

  $ hg ci -m local

  $ hg tracked -q --addinclude d0 --addinclude d9

Widening preserves bookmarks

  $ cd ..
  $ hg clone -q --narrow ssh://user@dummy/upstream narrow-bookmarks --include d4
  $ cd narrow-bookmarks
  $ echo local > d4/f
  $ hg ci -m local
  $ hg bookmarks bookmark
  $ hg bookmarks
