Pratham Gandhi 2fe492891f Fixed cursor position and undo/redo merges 
Fixes two things:

1. Cursor positions are being incorrectly calculated in scenarios where keystroke actions reject some input text.
2. Undo/redo operations were buggy and the commands would not merge often leading to single character undo/redo most of the times.
