6934	[PATCH] django.core.urlresolvers.reverse fails sometimes.	Sebastian Noack	nobody	"If you have a url pattern, containing...

- nested groups
- not-matching groups
- look-ahead or look-behind groups

...django.core.urlresolvers.reverse will fail, because of following reasons:

- To replace the groups re.sub with r'\(([^)]+)\)' is used, which matches only until the first ')', doesn't matter how much groups are nested.
- All groups which are no named groups are assumed to be positional groups, regardless if they might be not-matching, look-ahead or look-behind groups."		new	HTTP handling	dev					Unreviewed	1	0	0		0	0
