- Fix wrong selection when text is moved down
- Allow drop into own area, but is only noticable when copy, not move
- Code looks simpler, I think
- Autotest looks good
- Please see (and comment) code comments
TODO/Help is appreciated
- Cursor is wrong placed after undo
- Block mode after selection is buggy when mixed tab+spaces are involved
- Rename some variables, like targetCursor/2
