Quoting quotes automatically should be default
or just even possible
Badspot blocked quotes from being automatically included in quotes via the quote button because people were both unintentionally and intentionally making massive quote chains which REALLY forgeted up pages after a while. He didn't remove the ability for quotes to be inside quotes, but automatically quoting via the button removes quotes from inside.
... It's weird I remember that. That was so many years ago, back around the time I first joined or so? Give it a year or two, but still a long time ago.
