tmux: How to create a new window with the same path (from the current pane)

[Atanas Vladimirov]

Hello,

The following works on Linux:

```
bind c new-window -c "#{pane_current_path}"

```

but the `pane_current_path` variable does not exists on OpenBSD.
Does anyone now how can I achieve the same behavior on OpenBSD?

Many thanks,
Atanas
