Actually I think, "Outlet 0" is easier to parse with Pd: [route Outlet]-[route
0 1 2 3]. Having a separator like the ":" makes reading easier. I guess, for
Pd parsing padding that with spaces would help and not hinder readability that
much. 

So outlet comments could look like: 
 
 Outlet 0 : left stereo signal
 Outlet 1 : right stereo signal

I will for now continue to not use a space, and when I'm done, run a regex over
them.

I *really* want multiple-word tags. :) So a separator is needed, but one
without Pd-meaning could be used, like "-".

Anyway, many values use commas already, because they are written in natural
language which has commas so the parser should be aware of them.
