For future reference: Files with content by js before the meeting with Niklaus Giger 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 previous versions of my own code, and may have introduced small problems while refactoring. So I mostly went back to my previous versions, but kept both variants in these files. I may remove excess and js specific material etc. as begun by Niklaus as soon as I have completed other work that has higher priority for me.
