1)internal check found a 'findmatch' with simple string argument;
...
2)Style: uniform 'while (...)' when inside it there's an assignment;
3)Replace '0' with 'NULL' where there's comparison with a pointer.

Fix ticket #3317 (same expression false positives)
...
Add a check for function calls that have no side effects. That means
known const methods and a list including strcmp, strlen, etc.
If the function is not known to be side effect-free then no style
warning is given.
Add test cases for the duplicate expressions.

Change every 'tokAt(1)' to 'next()' and every 'tokAt(-1)' to 'previous()'.

Added a safety check to ensure that a 'previous()' call doesn't crash (not sure if it's needed or not).

Change every 'tokAt(1)->' to 'next()->' because 'tokAt(1) == 0' is equivalent to 'next() == 0', hence the equivalent cppcheck crash.

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.
