Readline-style history search

[prg]

So I've typed this one long command into the console a while ago and now would like to run it again. I still remember it contained the string "foo". Would be great if I could just type "ctrl+r foo" instead of hitting the up key dozens of times or switching to a terminal and running "grep foo player-data.json".

This would be really sweet, anyone who's gotten used to a readline-enabled console is permanently grumpy at having to do without, like living with a permanent headache and no coffee. First-world problems, I know, I know.
