Phil, I tend to agree with Ed that I think something was spilled on them. This reminds me of a piano I serviced several months ago. About four years ago it had been restrung by a rebuilder not far from here, and the owner told me her young daughter broke a vase and some of the water went on the strings. Some of the wound strings had corroded to the point that the core wire broke. I had never seen anything like it before. It looked like what you are describing. It is possible that the affected strings will eventually break for you as well, although I hope not.
