I'd better fix that bug if I'm getting a tshirt for it.

This operates at the cell level, even if the user disables multiline_history in the terminal, so you can define a multiline function twice, and only have to flip through it once after you start a new session.

There's an added bonus fix for setting the next input at the terminal on Python 3.

Aside: the equivalent thing also needs fixing in the Qt console. I'll see if I can track down the relevant code and add it to this PR.

Found the relevant bit for the Qt console too.

You can eliminate these three strip()/rstrip() calls by using a single stripped = cell.rstrip(), and if stripped and stripped != last_cell:, yes?

Good point. Done.

Looks great, works great, and fixes a really annoying little regression.

Great job, as always. Totally deserving of the issue #1000 award!! :) Will merge now, thanks a lot.
