From b799cb4c0eebb0762e91e9653d8b9cc9a98440e3 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 23 Sep 2008 10:05:02 -0500 Subject: Expose command table search for sub-commands Sub-command can benefit from using the same table and search functions that top level commands have. Expose this functionality by refactoring find_cmd() and introducing find_cmd_tbl() that sub-command processing can call.
