23460	Allow a literal `%s` to be passed through extra select	Matt Robenolt	nobody	"Right now, if you try and do something like this:

{{{
Foo.objects.extra(select={'foo': ""'%%s""'})
}}}

or

{{{
Foo.objects.extra(select={'foo': '""%s""'})
}}}

Ultimately `add_extra` raises a `StopIteration` while iterating over `param_iter` since there aren't actually any arguments to format.

It's expected to allow %%s as an escape sequence.
