httpd translates %xx and generates a false QUERY_STRING for cgi scripts.

[Dirk Clemens]

The httpd translates %xx sequences in the query string into the
ascii representation. But this is bad, because a cgi programm must
distinguish between '&' and '%26' and other chars with special meanings.

Expample:
If you try http://my-server/cgi-bin/test?name=a%26b
the query string becomes name=a&b.
And this means, that we have two Parameters:
  name=a
and
  b (withaout value)

The correct interpretation is:
  name=a%26b

The translation is normally done after the splitting of the
query string in the cgi programm.
