As I told you yesterday (privately), Commercial Emacs performs much worse 
than what is now on master with respect to that bug.

> The proposer of the GNU Emacs fix even paraphrased Commercial Emacs

???  I did not even know that a proposed fix existed in "Commercial 
Emacs".  And how could your proposed fix have been an inspiration in any 
way?  As you yourself write two lines above you "do not resort to the 
blunt instrument of narrowing".

To be clear, you seem to be.
