Comment #6 on issue 3682 by
[hidden email]: multiple undo/redo is
broken in 1.2 because of Ocompletion.
http://code.google.com/p/pharo/issues/detail?id=3682yes, 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
