Request completed: soon after I posted the expanded and improved answer, members were kind enough to undelete. Your guidance and prompt response is much appreciated.
Edited: I have substantially edited, expanded and improved my recently deleted old answer to conform to current site expectations of quality. Kindly vote to undelete or explain how to further improve my answer to get it undeleted.
As expected, my recently-accepted-and-highly-downvoted 4-month-old answer got deleted. Now the delete-voters can help me by explaining the reasons for deleting this answer after it was accepted by OP. Meta.SE says that poor answers need only be downvoted, and only very low quality posts need to be deleted, but I am not especially proud of the original short answer and I am willing to improve the answer towards getting it undeleted: however, you got to tell me what's wrong with it!
Answers are especially welcome from the 3 delete-voters here because you can vote to delete again if somebody else votes to undelete. So you are the ones who must really be satisfied that my revised and expanded answer can be undeleted.
Many thanks to @Tinkeringbell and @Catija for providing useful feedback that helped me understand how this answer needs to be improved to satisfy current site expectations of quality, towards undeletion.
