+
+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.
+
+Also tested are "git add -u" without limiting, and "git add -u"
+without contents changes, and other conditions'
