Initialize temporary line structures properly
Apparently, not initializing all elements of a struct can lead to random
problems if something somewhere decides it should reference one of those
uninitialized fields. Who knew. Set the temporary line_t structure to zeroes
before passing it into anything when calculating the stuff for "object"
output which should at least make things predictable.
This seems to fix a crash reported by "strick" in Discord.
