[Python-markdown-discuss] Default Pattern regular expression

[David W. <wo...@cs...>]

At the moment, the Pattern class defaults to using the regular  
expression ``^(.*)<user patter>(.*)$`` to match everything.  This  
becomes problematic, however, if the user's pattern has an optional  
prefix (ie: ``(\!?stuff)`` -- the ! (if it exists) will be matched as  
part of the (.*) instead of the (\!?stuff)).

I've replaced the regular expression with ``^(.*?)%s(.*?)$`` -- the  
non-greedy sides should do the trick (at least in my situation).

Now, is there any reason this shouldn't be used generally?  I can't  
think of any expression which it would break... But,  admittedly, my  
regex-foo is low.

Thanks,
David
