Applied with light editorialization. The main non-cosmetic change
I made was to postpone selection of default line_style until runtime
(see get_line_style() in the committed patch). The original coding
required knowledge of the line_style default rule not only in three
different places in psql, but in every other place using print.c,
such as createlang/droplang -l (which dumped core with the patch as
submitted). I changed it so that leaving line_style NULL implies
the default encoding-driven behavior, so that we don't need to touch
any of the callers.
