For future reference: Files with content by js before the meeting jsigle-ngiger and after subsequent consolidation and refactoring by Niklaus into 2.1.7.1.rc4. Niklaus did, however, remove some of my hires monitoring output, extra informative comments, automatic comparability with previoius versions of my own code, and may have introduced small problems from refactoring. So I mostly went back to my previous versions, but kept both variants in these files. I may remove excess material etc. as begun by Niklaus as soon as I have completed other work that has higher priority for me.
