New Revision: 47662

URL: http://svn.digium.com/view/asterisk?view=rev&rev=47662
Log:
move "core set debug" to the new style, and remove duplicated
code for the deprecated handler.

On passing fix a long standing bug in find_cli() which would not
find the longest match - this part (trivial, basically
just update matchlen on a match) must go in 1.4 and possibly 1.2 as well.
