Can you really just call a bunch of completions in series and get a
useful result? The documentation still seems to imply running will
stop as soon as one hook returns 0 status.

More importantly, shouldn't you only run zsh_directory_name if that
function exists? As it is now, it will be run even if only the array
is defined. Also, why the mix of -n $foo and ${+foo}?

% ls ~[<tab>_dynamic_directory_name:8: command not found: zsh_directory_name
