[IPython-dev] pasting lines with "\" into ipython

Hi Ondrej,

I don't know the exact answer, however if you put the comma after back-slash
on a new line it works.

In [10]: from hermes2d import Mesh, H1Shapeset, PrecalcShapeset, H1Space \
   ....: ,WeakForm, Solution, ScalarView, LinSystem, DummySolver

and IPython complains about a missing module as expected other than a syntax
error :)
