[PATCH 1/1] pane_current_command: fix segfault

[Thomas Adam]

When trying to call splitw from a zoomed pane due to running
'choose-tree', tmux will segfault as the default format will try and
access wp->shell which isn't initialised.

Skip this in the format's current_command callback as we can't do
anything useful with it anyway.
