You should rename it to justify-two-columns-lines then
Great..
I see that when the text is long, I must play with the value in:
\override-lines #'(amount . 115)
See attached example. Guessing the right number was easy in this simple
one page example. But in a bigger text this is not easy at all and the
result is: the first few pages are correct, then the text flows on one
column only until the end.
