Hi,

I'm working with django-tagging and for simplicity while testing and 
prototyping I have been using urlencoded-tags in URLs (seems that is about to 
change*, so this likely will be moot for me).

When a tag contains a comma i.e. "smith, john" it gets encoded and works fine 
_until_ I want to specifically identify it within a URL conf.

    url(r'^/(?P<tag>[\w\d \-\+,]+)/$'...

Will not work (nor will escaping the comma).

Any ideas, comments or suggestiosn about this?

Thanks

S

PS: I also discovered that non-greedy syntax does not _appear_ to work i.e.
        /[\w\d]+?/
    
    will select both
        /path/name/
        
    and not just
        /path/ 
        or 
        /name/ 
        
    depending upon the rest of the string, of course. The
    classic example is the pattern '\<.*\>'  will match
    everything on this following string.
    
        <span>Some text</span>
        
    but '\<.*?\>' will only match <span>
    
    
* I have a bunch of 'knowledge' stored hierarchically regarding tags (or 
keywords) so the idea of a simple set of tags is falling apart. Yes, some of 
that is possible by unions & intersections, but some isn't 8^(
