[PATCH 006/18] kdb-expand-dupl-cmd-error-msg

Expand the KDB 'duplicate command' error message.

Make more informative the error message that KDB prints out
when an attempt is made to register a new KDB command that
has the same name as an already-registered KDB command.
The new message prints the name, etc of the offending
command.  This makes it easier to find the culprit.
