I think that a single tool that allows you to edit various config files
preserving the validity of the syntax has its uses. Yes, it would be easier
to shoot yourself in the foot than if using the tools provided with the
distribution, but a single interface for changing name/value pairs in
different config files is priceless.

Anyway, documenting the ability to use '#' for comments in apt config files
should suffice. It will provide ground for pushing changes to other
projects parsing the apt config files.

Thanks,
Stoyan
