A small enhancement to the automatic )'s in 3.6:

I often find myself modifying a line such as:

System.out.println ("Thingy: " + c.getClass().getName());
                                                 ^

by putting the caret at the ^ and changing it to:

System.out.println ("Thingy: " + (c != null ? c.getClass.getName() 
: "null")));

When I type the closing ) for the ? : clause, it just overwrites the 
existing ), so none is added.  This is non-optimal, because I end 
up retyping the rest of the )'s so I can add one at the end.

Two possibilities for handling this situation:

1.  (simple) - detect if all the remaining characters on the line 
are )'s followed by a ; and if so, allow the insertion.

2. (not as simple) - detect if there are an unbalanced number of 
parentheses on the line (possibly handling split lines?) and allow 
the insertion if it will make them balance
