New Revision: 235902

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=235902
Log:
Prevent consecutive duplicates from appearing in CC_INTERFACES.

If dialing, say, a group of DAHDI channels, it's possible that
there are multiple devices or PRI spans that will be monitored
to determine when a member of that group has become available.
When the time comes, we don't want to end up with a CC_INTERFACES
variable with contents like

DAHDI/G1&DAHDI/G1&DAHDI/G1

Instead, just one will suffice.
