pub fn lines(all: &[Line], seen: &Seen, l: &Lister<'_>) -> Vec<PorchLine>Expand description
The Porch’s lines, oldest first: the messages of the last week not seen
on any device, once the phone let them through and while their sender
may reach you; never a blocked sender’s. One line per phone,
conversation (or sender), part of the day and day; a code its own line.
all are every phone’s (read_logs), oldest first.
