protected function DatabaseCondition::ensureBrackets

Ensures that the value being tested against is bracketed.

Some operators don't usually need brackets around the value being tested, but when the value being tested is a SelectQueryInterface it needs to be bracketed. This function adds those necessary brackets.

Return value
