Dear APT Maintainer, APT::Never-MarkAuto-Sections obviously has quite some unexpected impact on apt-get's and aptitude's behaviour (see e.g. https://bugs.debian.org/776785 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756816#27), but so far it's only documented in /usr/share/doc/apt/examples/configure-index.gz Please document APT::Never-MarkAuto-Sections also in the man page apt.conf(5) and refer to /etc/apt/apt.conf.d/01autoremove as file to edit.
