Ok, so this means the 'fix' isn't really one, as I feared.  This annoys me to 
no end, but I have no idea how to fix it.  I would _guess_ the problem lies 
with the cygwin readline itself, since every other terminal under 
Unix/Linux/OSX seems to handle these things correctly.  But I may be wrong, 
I'm just shooting in the dark here.

Until a cygwin guru can suggest a true fix which doesn't break line wrapping, 
I'm very much afraid we'll have a standing bug under cygwin. Bummer.

Fixed (slightly different form, same effect).  Thanks.

Yes, gnuplot.py does require a bit of manual customization straight into the 
source.  That part is beyond ipython's control, you did the right thing.
