[New-bugs-announce] [issue24661] CGIHTTPServer: premature unescaping of query string

New submission from John S:

I created a simple CGI script that outputs the query string passed to it:

#!/usr/bin/env python
import os
print 'Content-Type: text/html\n\n'
print os.environ['QUERY_STRING']
I saved it as cgi-bin/test.cgi and made it executable. I then ran `python -m CGIHTTPModule` and opened 
in a web browser.

The output was H&M when it should have been H%26M

I tried with Python 2.7.5, 2.7.3 and 2.6.6 and they all correctly output H%26M.

The test.cgi file is attached.
