We have no idea why this was even a thing. For now simply set it to "all"/"full" (why these two names? no idea) at startup and allow changing it later. Settting it *immediately* when defining the variable sets it too soon because we don't have the interactive signal handlers enabled (including the one for SIGTTOU), so let's first settle for this little piece of awkwardness. This needs widespread testing, so we merge it early, immediately after the release. Fixes #5036 Fixes #5832 Fixes #7721 (and probably numerous others)
