test_description='git add -u with path limiting

This test creates a working tree state with three files:

  top (previously committed, modified)
  dir/sub (previously committed, modified)
  dir/other (untracked)

and issues a git add -u with path limiting on "dir" to add
only the updates to dir/sub.'
