Comment #6 on issue 3682 by [email protected]: multiple undo/redo is broken in 1.2 because of Ocompletion.

yes, I think that all ocompletion extension methods in SmalltalkEditor should be integrated in the core. as an example, #caret should be in TextEditor and rewritten to simply return startIndex.
selectInvisibilityAt should also be in 1.2 core so that the ocompletion fix becomes loadable in 1.2
