Introduce `history_since_<id>` value expansion
The `history_since_<id>` value expansion allows incremental parsing of a
buffer's history.
declare-option int my_last_history_id
define-command my-process-history ...
# process the initial buffer history
my-process-history %val{bufname} 0 %val{history}
set-option buffer my_last_history_id 0
# only process new history changes on idle
hook buffer NormalIdle %{
evaluate-commands %exp{
my-process-history \
%%val{bufname} \
%%opt{my_last_history_id} \
%%val{history_since_%opt{my_last_history_id}}
}
set-option buffer my_last_history_id %val{history_id}
}
