The incident mention in the quote got me wondering why that wall wart would no longer work, so, with only a little difficulty, I managed to open the case and discovered....a glass-encased fuse, similar to those formerly used in automobiles, which the short caused when the two wires touched, blew the fuse.

I unsoldered it from the circuit board, and replaced it with...an automotive fuse of similar rating.  It's now functioning as before.

All wall warts have some kind of fuse. Some simply have a thin wire that acts like a fuse, those are almost impossible to repair. I've taken larger ones that had room and attached a fuse holder to the case. Now I have a fuse that's easily replaceable.
