[asterisk-users] Patch for app_dial.c: exit when just one ext is busy.

[Leif Neland]

I made a patch to app_dial.c to make Dial(ext1&ext2&ext3,tumeout,B) 
return busy when just one extension is busy.
http://www.neland.dk/app_dial.c.diff
It works, but...

I can't figure out setting/reading an option.
It looks fairly easy, but the flag is always set.
