+/// 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.
