+# Handling of cd.
+#  - Normally just completes directories.  Uses cdpath if that's set
+#    and the string doesn't begin with ~, /, ./ or ../.
+#  - In the second argument to cd for the form `cd old new', completes
+#    possible `new' strings by examining `old' and $PWD.
+#  - After - or +, completes numbers, but the listing
+#    gives you the list of directories to complete.  This turns on
+#    menu-completion and lists the possibilities automatically, otherwise
+#    it's not a lot of use.  If you don't type the + or - it will
+#    complete directories as normal.
