Fix for same expression separated by commas
...
The code branch tested by the previous check for && is now different, so
I've changed the test to use == instead. There was also a missing case
when the expression was followed by a comma instead of being preceded by
one.

Improved same expression check for ticket #3274
...
Expand the logic for the check for the same expression on both sides of
the || and && operators. Now expressions can be more complex, with the
"alt" variable helping to fudge operator precedence to avoid false
positives.

Fix namespaced types for auto_ptr new[] errors
...
This fixes false negatives for code such as:
std::auto_ptr<foo::bar> p(new foo::bar[10]);
The idea is to find a "new", search for the end token ";", then see if
the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.
