I'm a c++ programer, and sometimes I need to initialize lots of member fields 
during in a constructor. Sometimes when the init list is too long, cc mode will 
treat some member-init-cont as topmost-init-cont, and then gives a wrong 
indention. 

After some debuging, I found this change: 

http://lists.gnu.org/archive/html/emacs-diffs/2012-03/msg00152.html.

In this change, In CASE 5B, search limit is restricted to 500. This, sometimes, 
is not enough.

Best Regards
