Moving the cursor around in long lines that are automatically split does not work. 

Reproducible: Always

Steps to Reproduce:
1. Open konsole, paste a long line (without newlines) that will spawn more than one line in konsole
2. Try to move the cursor by e.g. Left key
3. Paste again, press Up key

Actual Results:  
For 2., cursor cannot move beyond the first character of the last line. It just stays there
For 3., The cursor will still stay in the last line. Fragments of the right text is shown in the column where the prompt ends



Expected Results:  
One should be free to navigate in longer commands spawning multiple lines. 

Prompt is "\[$(ppwd)\]\u@\h:\w>" (system default)
