[IPython-dev] minor ipython.el news

Ok, thanks for this.  I just uploaded into:

http://ipython.scipy.org/dist/ipython-emacs-0.3.tgz

a tarball with the currently official python-mode from sourceforge and the 
ipython.el file you sent as well.

Hmm.  I poked around ultraTB.py, which is the traceback formatting code, and 
it looks doable.  However, not particularly straightforward at first sight :( 
  That code is rather convoluted, and I'm not super-familiar with it, since I 
didn't originally write it myself (though I've modified it quite a bit).  So 
don't hold your breath on this one.  However, if in your copious spare time 
you come up with a nice patch for it, I'll gladly include it in ;-)

This one looks more feasible: it's basically adding more sophisticated quoting 
to @run than the simple .split() it currently does (I mean for the quoting, 
globbing is even easier).  I'll see if I can get this one in soonish, to at 
least grant you one of your wishes :)

I hope your health improves.

Cheers,
