Comment 5 for bug 194156

To partially fix the original bug... when author column is created inside DocumentView, you can change its expand atribute to true and get a working left-hand divider.

In referencer hg 1.1.5, open src/DocumentView.C, go to line 1476 and change

addColumn ("author", _("Author"), docauthorscol_, false, true);

by

addColumn ("author", _("Author"), docauthorscol_, true, true);

Not perfect, but you get a working left-hand divider for author column... a little bit more intuitive.
