REPL multi-line history

[metametadata]

It could be convenient to have some key combo (e.g. Option+Up on MacOS) which would copy-paste the last submitted string (i.e. everything typed before last Enter):

cljs.user=> [123<<Shift+Enter>>
       #_=>  456]<<Enter>>
[123 456]
cljs.user=> <<Opt+Up>>[123
#_=> 456]
