Good point - I can make the # of passes in the loop a variable w/ the default 
as 2.

However, for now, would you agree that the two-pass solution is better than the 
alternative (too-wide / too-narrow spacing)?  Although I don't have much 
feedback for where this would be useful, the one person who has given this code 
a spin (Bertrand) and who is pretty invested in all things footnote seems to 
like this system over a one-pass alternative (I'm not putting words into your 
mouth, am I, Bertrand?).
