+ * Added selection functionality, and adjusted key bindings:

+ - + and - adjust the selection using shell globs;
+ - t and T insert the selection into the external command line
+ in relative or absolute form, respectively;
+ - Enter is like t but enters directories, and M-Enter is synonymous to t;
+ - C-g or Escape clear the selection, similarly to the editor.
+
+ * Added an sdn-view script that can process Midnight Commander mc.ext.ini files
+ and apply matching filters; this script has been made the default F3 binding,
+ while the original direct pager invocation has been moved to F13 (which also
