 Reports invalid alignment of JSDoc block lines. This is a

+#### Options
+
+This rule allows one optional string argument. If it is `"always"` then a
+problem is raised when the lines are not aligned. If it is `"never"` then
+a problem should be raised when there is more than one space between the
+lines parts. Only the non-default `"always"` is implemented for now.
