1. M-x text-scale-increase (7 times)
2. Go to column 4.
3. (posn-col-row (posn-at-point))
=> (15 . 24)

Alternatively, please describe how to reliably recalculate the returned
value in the presence of text-scale-mode.

Then I'll have the return value of `posn-col-row' dependent on the 
buffer contents, but hopefully independent of the text scale level.

Thank you, but you seem intent on helping me write the code in a 
considerably different way than it's written now. That would indeed be a 
waste of time, like Stefan said, because it mostly works well enough.

Closing.
