Thanks for the patch!

But i am not sure if this is a good idea. Adding it this way means that the
commandline -o looks more like it would support the same syntax as a
configuration file does, but differences exist:
Statements do (not) end with a semicolon, scope-usage is (dis)allowed,
the syntax to set an option is (not) config::option=value, …
Also a -c for including additional configfiles exist, but if we support #clear
in -o we should properly add #include, too…

All in all i think a --clear(-option) option would be better.
What do you think?

P.S.: I am pretty sure -o "#clear …" never worked in apt-get.
