-test_description='git-add -u with path limiting
+test_description='git add -u
This test creates a working tree state with three files:
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.'
+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.'
