Does (or did) this really have the effect described in the comment? It
seems to me that this would have used extent-based spacing, so the lines
ooooo
yyyyy
lllll
would be unevenly spaced. Anyway, I can certainly reinstate this. It
will just need some changes to Page_layout_problem::append_prob
(whatever properties are set in Paper_book::get_system_specs need to be
read in Page_layout_problem::append_prob and they should be used to
modify the spring).
