How can I make pushd autocomplete CDPATH entries?

Question

I have bash-completion installed, and I get a lot of mileage out of tab-completing CDPATH entries when using cd. I'd like to get the same functionality from pushd. I started diving into the bash-completion source code, but I'm a little out of my depth.

Try adding this to your .bash_profile:

# Taken from /usr/share/bash-completion/bash_completion on my
# Ubuntu 16.04 system, substituting "pushd" for "cd":
if shopt -q cdable_vars; then
    complete -v -F _cd -o nospace pushd
else
    complete -F _cd -o nospace pushd
fi

Works for me. Note that it's indented, as it's "protected" by an if [ -n "$PS1" ], to ensure it doesn't run for a non-interactive session. (My .bashrc run .bash_profile to handle some ways that shells are started, such as via ESC-x shell in GNU Emacs, which reads only .bashrc.)
