Nicolas Palix49ab7a32010-08-24 17:39:12 +02001/// Find confusingly indented code in or after an if. An if branch should
2/// be indented. The code following an if should not be indented.
3/// Sometimes, code after an if that is indented is actually intended to be
4/// part of the if branch.
5///
6/// This has a high rate of false positives, because Coccinelle's column
7/// calculation does not distinguish between spaces and tabs, so code that
8/// is not visually aligned may be considered to be in the same column.
