   Allow to extend reduced thin volumes with external origins.
   Consider snapshot and origin LV as unusable if its component is suspended.
   Fix lvmconfig segfault on settings with undefined default value (2.02.120).
+  Add explicit 's' (shared) activation mode.
+  Ignore hyphens in long options names (i.e. --long-option == --longoption).
