[IPython-dev] Regression bug in 0.8.x input filtering

[Dan Milstein]

Hmm.  I can, I think without too much pain, force whitespace between  
the possible magic/alias/autocall term and the rest of the line, but  
I am just a bit hesitant, because I think that's sort of new  
behavior.  The old pattern matching was very, very hard to fully  
comprehend, but I don't think that's what it did (at least, not in  
general).  I mean, if this is a regression, clearly it did  
*something* like that, but I'd like to fully understand it before I  
make a serious change like that.

(Or maybe people like Ville's fine, fine idea about getting rid of %r  
as a magic -- IMHO, we're kind of asking for trouble given that  
r'something' is valid python).

Also Hans: can you resend the original email to me?  I can't see to  
find it, for some reason.
