Support for pushd and popd?

[onlyanegg]

I use the directory stack a lot, so it'd be great to have support for pushd and popd. I can see that there's a PR for it.

@onlyanegg Agree that the PR is open for the change. I haven't really got time to test it and has a few conflicts.
Thanks for raising this, I'll see if I can test in the coming days.
