+# 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.
