Hmmm, '&' is already encoded in request (see mutantUrlParts.py)
May be it is because how PHP processing of it? In our xss_tests I see
one problem - each of them consists of too many special chars which can
be filtered and make different output in response. To exploit XSS
usually it is enough to have <>()= plus " or ' character. What I worry
about is with such complex strings we can miss existing flaw.

Fixed.

Ok, I forget about it :( Fixed test script and added PHP files to
testEnv/webroot/w3af/core/fuzzURLParts/
