--- Comment #7 from Ricardo Abreu <ricardolafabreu at gmail dot com> --- Yes, the very next paragraph directs to tens of other paragraphs that mention other switches. One has to read them SFINAE mode to discover the special meaning of the general text. That may be considered strictly correct, but it is still not very good documentation. It is bound to mislead many readers. Usually CLI switches aren't silently inoperative until you provide other switches. That is a questionable UI decision to begin with, if you ask me. How can you say that expecting a switch to actually turn something on is trying really hard to find alternative meanings? It all seems pretty obvious really, I am only having to try hard explaining because you are trying so hard to dismiss it.
