Hi again everyone,
Here's hoping a second question so soon will be okay.
I'm trying to add a sidebar (a margin rule) to the outer margin of my
doublesided layout.
This sidebar is bound to a specific kind of section that uses columns
with balance=no.
In the working example below, the sidebar on the second page goes as far
as the length of the second column, which is shorter than the leftmost one.
I'd like the sidebar to follow the length of the longest column.
Is there a different approach to this?

Easiest is to add a 'command' option so that you can plug in whatever
you like but first Wolfgang needs to check this for possible interferences.
