  /// Find confusingly indented code in or after an if.  An if branch should
  /// be indented.  The code following an if should not be indented.
  /// Sometimes, code after an if that is indented is actually intended to be
  /// part of the if branch.
  ///
  /// This has a high rate of false positives, because Coccinelle's column
  /// calculation does not distinguish between spaces and tabs, so code that
  /// is not visually aligned may be considered to be in the same column.
