This shows a shell-like history of searches and the most recent --stdin
edit. History is numbered with the most recent action being 1, and the
earlier actions being of a higher number until the maximum amount of lines
set in the HISTORY variable in swimrc(5).  A separate history is
kept for each architecture-distribution.
