I attempted to add a new hook to the autocmd subsystem to allow me to bind
actions to the current working directory changing.
Attached is my attempt, I also tried patching ex_cd in desperation while it
wasn't working. I think my issue is in the way I'm invoking apply_autocmds,
but
this seems to be the right approach. I would appreciate pointers in the
right
direction.
Thanks.
