Sure you can find when a line was added - but I want to know where the line came from
Suppose I browse to some web page - select some text and put it in the “cut” buffer
then I paste this text into a file that I’m editing - all the editor knows is that the
text came from the cut-and-paste buffer and NOT the web page that I cut-and-paste from.
After the event when I read (or somebody else reads) the text they might be left wondering “where the heck did this data come from” - I’d like to drill down and find out exactly where everything came from.
Editors just record keystrokes - but they don’t know or care or record where the data came from - so one of the most important questions “how the heck did the author of this text get the necessary information to write this text” is not answered.
