Fix Kdebug - new event line for each comment

Currently Kdebug is concatenating all K line commands together in one long string that grows with every K line command, that quickly leads to serious slow downs whilst viewing the Event viewer.
It also makes it time sapping to view new comments as you have to scroll to the far right of the line.
What would be better is if each K line command was split on the null terminator , it would be far more readable and avoid the slowdowns.
