In some cases, when we handle SyntaxErrors we need to ensure that the column number is correct for a 1-indexed report. In some cases, we also need to account for the fact that the SyntaxError has happened "after" a new-line. To extract and alter the row and column numbers, we've moved the logic to a private static method on the FileChecker object to avoid an overly complex method. Closes #237
