event), or to -16 if the tt(-l) flag is given.
If var(last) is not specified, it will be set to var(first),
or to -1 if the tt(-l) flag is given.
However, if the current event has added entries to the history with
`tt(print -s)' or `tt(fc -R)', then the default var(last) for tt(-l)
includes all new history entries since the current event began.

flag tt(-n) suppresses command numbers when listing.
