You should set &verbosefile option in --cmd.

You can use :debug or use &verbose with &verbosefile, but I doubt this will help. These are helpful if you need to determine what and why is run, but much less helpful if you need to determine why something is *not* run.

Note that &verbose option may change execution flow, same for :debug. Specifically they are not compatible with some NERDTree functions if they are called inside :try: both &verbose and :debug try to dump returned values under certain circumstances and when they try to do this with recursive (containing themselves) data structures they fail because they use string() code. This failure when happened inside :try is transformed into an exception. I also think (but have not actually checked) that this failure also affects :redir.
