Hmmm... first, such a message should not be in there, unless it was
left in from a good while back, when I had someone helping me test things.
I'll look as I don't really want crafty cursing anyone when it screws up.

Found the code...  that was part of the debugging for the "drawn ending
tablebase swindle" code.  You can ignore it...  but here is the deal:

*if* you download KRP vs KR, you must download *all* the KR*KR files.  Or
it will *not* play reasonably...  my stock advice:

download all the 3/4 piece files, or else download none.  Download all the
5 piece files on my ftp machine or stick with the 4's...  the 5 piece files
I have are all needed fo rKRP vs KR endings...
