#compdef cd chdir pushd

# 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.
