I have implemented k now such that in combination with c it disables capture of royals. (A combination that before was not different from plain c.)

Actually this means that k now can do what the t modifier (for 'tame') does in XBoard. Without using an extra letter!

In the process of testing it I found out there was a horrible e.p. bug in the AI of the Interactive Diagram: it was always considering the destination of any normal moves an e.p. square. But since usually pieces that can e.p.-capture also would have normal capture to the same square, it would not have any effect other than that the capture would be generated twice. With the new move entry routine this would require an extra click on the destination, though, to resolve the 'ambiguity'.
