I'm kind of surprised that this works.
Basically, the idea is that you tag the syllable you want the column to
left-align to by overriding an invented property which I called `tagged'
for lack of any inspiration.
Right now, you need to choose the syllable you want to use for alignment.
I don't imagine it would be difficult to determine the longest
automatically.
The materials between %%%% aren't strictly necessary. Without them, you'll
just get a number of warnings.
Hope this helps!
