simplifyIfAddBraces: Remove restriction for jumping opening parenthesis '(' as a fix to #2873, because even without this the original test case doesn't crash anymore. Add more jumping patterns. 

simplifyFunctionParameters: Add more jumping patterns and an observation related to error message for equal parameter names, help needed.
Fix grammar mistake in comment.
