I wonder if we still got feedback I should attend to before we can do 4.6.0. After some feedback on WinBoard I fixed the splittingof the debug file when used in cobination with a loadGameFile, and in the process encountered some verbose debug output in that code, which I removed too.
I also discovered that sweep selection did not work with the middle button (and I don't even have one!) Now I think we nver promised that it would, but the old piece menu did use button 2 for white, so it seemed better to restore the equivalence of button 2 and 3, which I did. I also fixed two other minor inconveniences in EditPosition mode (the dropped piece remaining selected, so it would immediately move away on the next click, and the grab being limited to the board area). I pushed two new features now, (new command-line options), that seemed quite safe: they are very simple, can be guaranteed to not do anything when switched off (which is the default), and are used in rare situations anyway. Everything is in master; I did not touch 4.6.x.
