Here are the most common offenders (see the attached animated gif captures)

1. typing "default:" part of a switch statement will auto complete to "default::"

2. typing "else {" after an if

will auto complete to "else { }}", also breaking the indentation

Needless to say this is extremely jarring.

Also, it would be nice to have a option to disable this kind of auto-completion all together, while keeping the rest of the auto-completion functionality (as far as I can tell there's no way to disable this kind of built-in auto-completing w/o also disabling the identifier auto-completing)
