New Revision: 403414

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=403414
Log:
app_record: Add an option that allows DTMF '0' to act as an additional terminator

Using this terminator when active results in ${RECORD_STATUS} being set to
'OPERATOR' instead of 'DTMF'

(closes issue AFS-7)
