In historic vi, the previous context mark was always set:
ex address:
any number, <question-mark>, <slash>, <dollar-sign>,
<single-quote>, <backslash>
ex commands: undo, "z.", global, v
vi commands: (, ), {, }, %, [[, ]], ^]
nvi adds the vi command ^T to this list.

In historic vi, the previous context mark was set in non-visual
