Argh! You are right. It used to do that, but I broke it when implementing the Imitator. Both the Imitator and the move borrowing call the old move generator used for highlighting recursively. But for the imitator I added an extra argument, to restrict the moves of the target piece to the mode that you imitate (e.g. if you have a cI it should only imitate the captures). I had forgotten to pass this argument in the call for borrowing moves, and the missing argument then was interpreted as 0, so that you would never borrow anything.
Thanks for spotting this; I now fixed it.
The selective imitation does not really work satisfactorily anyway on multi-leg moves. Because it is not clear what are captures and what not. E.g. a Checker would have a capture in its first leg, and then a non-capture where it lands, and the selective imitation would now always reject one of the legs. While intuitively we think of the move as a capture (I think). So perhaps multi-leg moves should be considered captures when any of their legs makes a capture, no matter what the other legs do, for the purpose of selective imitation.
Not sure if there exist any CVs with selective imitation anyway, so this didn't have a very high priority...
