This is actually a major reworking of how the low level editor txns perturb selection. There is a mode now for telling the txns not to disturb the selection. There is also a fix for unlisting lists (sometimes list items got merged unintentionally when unlisting). git-svn-id: svn://10.0.0.236/trunk@56714 18797224-902f-48f8-a5cc-f745e15eee43
