Hi,
The pane_default_command test was incomplete in that patch. Here I
corrected it, and also implemented the feature I mentioned in the
previous mail. With this conditional replacement support variables as
values with #variable_name. And with this, I finally can get tmux
automatic renaming work as I wanted :D
Here is the patch:
