I'm sure it's not an ipython bug; ipython doesn't call readline directly.
The problem is that the multikey state is left on when the key sequence
context is disposed. I suspect a signal, but can't test this directly.
One difference between readline-6.2 and readline-6.3 is that readline-6.3
runs much less code (as little as possible) in a signal handler context.
Maybe the python code assumes too much about readline's signal handling
behavior. It may be a readline bug, but only python triggers it -- it
has to be some interaction between the two.
