Given that I'm the OP of this thread I feel entitled to officially closing it.
Those interested in my proposal will find my latest version of the patch in this new thread: https://marc.info/?t=169616631000001&r=1&w=2 For my part, what was said in this thread has already been assimilated and overcome. As my patches show, I heard and took into account every correction and suggestion (even though many, if not most, regardless of the intention with which they were made, functioned more as a boycott than as a contribution.) -- Walter
