 The defaults, spelled out in full, are:

 Vim puts a line in column 1 if:
 - It starts with '#' (preprocessor directives), if 'cinkeys' contains '#'.
 - It starts with a label (a keyword followed by ':', other than "case" and
-  "default").
+  "default") and 'cinoptions' does not contain an 'L' entry with a positive
+  value.
 - Any combination of indentations causes the line to have less than 0
   indentation.
