Yes, majorly annoying indeed (and it's awful that the two major linux
desktop terminal emulators both also have the bug, when 20+ years old
xterm gets it right).

Your wish is our command, Dr. Hunter; bug and solution:

https://bugs.launchpad.net/ipython/+bug/412339
https://code.launchpad.net/~ipython-dev/ipython/cpaste-fixes

In action:

In [2]: paste -e
x = 1
y = 2
print 'x, y:',x,y
## -- End pasted text --
x, y: 1 2

In [3]: paste
x, y: 1 2

In [4]: paste -r
Re-executing 'x = 1...' (30 chars)
x, y: 1 2

ps - you can safely merge from that branch into your working one.
Since Brian is in the middle of major reorganizations, this may take a
few days to get merged, as I don't want to get in his way.  But it's
localized enough that you can merge it for next week's tutorials
locally while we get it in place.
