27238	Disable check_pattern_startswith_slash if settings.APPEND_SLASH=False	Mathieu Comandon	Alasdair Nicol	"I would like to propose the removal of the check_pattern_startswith_slash system check as there are  legitimate reasons to have url patterns starting with a slash and this warning can be misleading.

The Django framework has a strong bias in favor of trailing slashes in URLs but not everyone wishes to set up their urls that way. If this warning was to be respected, it's impossible to have urls without a trailing slash in some situations: 


{{{
# myapp. urls
urlpatterns = [
    url(r'^dashboard', include('dashboard.urls')),
]

# dashboard.urls
urlpatterns = [
    url(r'^$', views.dashboard_home, name='dashboard_home'),
    url(r'^/users$', views.users, name='dashboard_users'),
]
}}}

The above URLconfs allow to have the URLs /dashboard and /dashboard/users but it will produce the warning. 

When trying to make the slash optional in the root URLconf with {{{r'^dashboard/?'}}}, the 2nd url will reverse to /dashboardusers.

I know that some system checks can be silenced but I'd be in favor of the complete removal of the check since it can be misleading for users who do not wish trailing slashes in their URLs.
