Use Arrow-Up to search history with prefix

[oberien]

If I type something, and then press the arrow up key, I'd like that to search through the history, finding the next command that starts with the same prefix as there is before the cursor. For example if I type the following:

> cd /a/really/long/path
> ls
> cd /another/really/long/path
> ls
> cd /a/ ⬆

I'd like to get the first command autocompleted. Another example:

> cd abcdef
> ls
> cd ab123
> ls
> cd abc ⬅ ⬆

In that example, my cursor will be after cd ab before the last c. When pressing up, I'd now like to have suggested cd ab123 and after another arrow-up-press I'd like to be suggested cd abcdef.

Is something like this already being worked on? Otherwise I'll try to implement it.
