pub fn history(
all: &[Line],
keys: &BTreeSet<String>,
l: &Lister<'_>,
) -> Vec<String>Expand description
A person’s messages of the week (keys, their numbers as Sioul keys
them), newest first, from every phone: a sentence each, for their sheet,
never a count; codes said without them, words withheld said so. A
blocked sender’s never come: they never leave the phone.
