filter option doesn't work when specified in /etc/portage/smart-live-rebuild.conf

[HJarausch]

If I set
f=!media-gfx/darktable,!media-gfx/skencil
in /etc/portage/smart-live-rebuild.conf
the second filter !media-gfx/skencil doesn't seem to get recognized.
Multiple "f=" options don't work either

It's my fault, I should have used
filter_packages=....

I'd like to suggest to add the following comments from config.py to the README file

color=True

config_file=/etc/portage/smart-live-rebuild.conf

debug=False

erraneous_merge=True

filter_packages=

jobs=1

pretend=False

profile=smart-live-rebuild

quickpkg=False

quiet=False

remote_only=False

setuid=str(pm_conf.userpriv_enabled)

timeout=0

type=

unprivileged_user=False
