New Revision: 402829

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=402829
Log:
Pickup: Pickup() and PickupChan() parameter parsing improvements.

* Made Pickup() and PickupChan() tollerate empty pickup values.  i.e., You
can now have Pickup(&&exten at context).

* Made PickupChan() use the standard option flag parsing code.
