output failure if first item in iterable is empty string

[GoogleCodeExporter]

Have the application return an iterable where the first item is an empty
string. wsgi_intercept will fail to process the remaining items in the
iterable.  The solution is to dedent by 1 level the following lines in the
"makefile function", so that the loop runs regardless of whether the first
element was an emptyt string: 

    while 1:
        data = self.result.next()
        self.output.write(data)
