+``resolve.mark-check``
+    Determines what level of checking :hg:`resolve --mark` will perform before
+    marking files as resolved. Valid values are ``none`, ``warn``, and
+    ``abort``. ``warn`` will output a warning listing the file(s) that still
+    have conflict markers in them, but will still mark everything resolved.
+    ``abort`` will output the same warning but will not mark things as resolved.
