if environ['SCRIPT_NAME'].startswith(self.to_strip):
environ['SCRIPT_NAME'] = environ['SCRIPT_NAME'][len(self.to_strip):]
'tricky' was changed to 'different' to offer a more neutral tone.
'some' was changed to 'no' and 'not properly' swapped with 'by default' to explain the difference.

Tested on nginx 0.7.x and 0.8.x
