Please send it to me once you have a chance.

But maybe you wrote "true" five times?

Any value other than "yes" and "no" is taken as "unknown".

I just copied old code I inherited from Sascha Böhm and his Vampire noncommercial. For sure there are endlessly many ways in which we could make Isabelle and Sledgehammer more user friendly. In Qt/C++, we had a "stripWhiteSpace" function that would do the trick. But string manipulation in ML is like pulling teeth. If you happen to know which function I can call, I'll gladly change the code.
