#928 SmartIndent doesn't add closing brackets properly

[Nguyen Viet]

When i tried to type "((" (double parentheses), the editor automatically add two parentheses "))".
But when i type "[[" (double brackets), the editor only add one closing bracket "]"

(())
[[]

I expect that the editor treat brackets as parentheses.
I'm using C::B svn 11979

Also, when i type "[]" (bracket) then type '(' (parenthesis) inside them, SmartIndent doesn't add closing parenthesis automatically
