Note that the text here is changed to "(this binding is currently
shadowed)", see Bug#14086.

Contrary to my hopes this part was in fact _not_ converted to Lisp with
the merge of scratch/substitute-command-keys.  This was due to poor
performance of my Lisp version of that code.  So this should be as easy
or hard as it was before to fix.

The text comes from describe_map in keymap.c (at the very end of the
function) if someone wants to take a stab at improving this.
