No, no, it still happens today. Maybe I am not finding the right words… The 
text cursor travels through every visible line of text, for example hitting the 
columns 12, 59, 107, … also these positions all belong to one long line of 
broken text. There is also no fixed rule by which the column number increases 
(or decreases when going towards the top of the buffer). This is really 
disturbing, I instantly assumed column-number-mode was broken.

And while I was testing this behaviour again it happened that I could not 
position by means of the mouse the cursor onto every column of a long broken 
line, i.e., most columns, for example those of the first part or the beginning 
of the broken line, could not be reached.

And there also lines segments containing the last part of a broken line that 
cannot be reached at all, neither with the mouse nor by using the cursor 
movement keys… 

And although I removed any white space on the lines after the (black) text had 
ended, I can see the cursor stay in that deleted white space:

But this could be due to customisation, AUCTeX, and using the NS variant. 
And/or having that text file open in two differently wide windows… Dead Can 
Dance and GNU Emacs can do magic with visual-line mode!
