[PD] route - pack issue

[Jonathan Wilkes]

[route] outputs an empty list which, for simplicity's sake, is supposed to be interpreted as a "bang" message.  But [pack] isn't doing this:

[list(
|
[pack]
|
[print]

Should be a pretty easy fix-- just check for an empty list in pack_list and if so, call pack_bang.
