reverse() and {% url %} don't work with slightly-more-advanced regexes

[albertpeschar@…]

This works fine:

# urls.py
urlpatterns = patters('ads.admanager.view',
    (r'^ad/(?P<id>\d+).html$', 'ad'),
)

# somewhere else (e.g. python manage.py shell)
from django.core.urlresolvers import reverse
url = reverse('ads.admanager.views.ad', kwargs={'id': 123}) # ad/123.html

Note that the regex used also matches e.g. ad/123xhtml , or any other character because of the "." that is not escaped.

This doesn't work:

# urls.py
urlpatterns = patters('ads.admanager.view',
    (r'^ad/(?P<id>\d+)\.html$', 'ad'), # <-- see the escape ( \. )
)

# somewhere else (e.g. python manage.py shell)
from django.core.urlresolvers import reverse
url = reverse('ads.admanager.views.ad', kwargs={'id': 123}) # ad/123\.html or ad/123%5C.html

---

Expected: ad/123.html
Got: ad/123\.html

And, yes, I used the SVN version ;-)
