+          Determines what level of checking 'hg update' will perform before
+          moving to a destination revision. Valid values are "abort", "none",
+          "linear", and "noconflict". "abort" always fails if the working
+          directory has uncommitted changes. "none" performs no checking, and
+          may result in a merge with uncommitted changes. "linear" allows any
+          update as long as it follows a straight line in the revision history,
+          and may trigger a merge with uncommitted changes. "noconflict" will
+          allow any update which would not trigger a merge with uncommitted
+          changes, if any are present. (default: "linear")
