Clarify precedence for template/style in commands.show_changeset(): Display format will be the first non-empty hit of: 1. option 'template' 2. option 'style' 3. [ui] setting 'logtemplate' 4. [ui] setting 'style' If all of these values are either the unset or the empty string, regular display via changeset_printer() is done.
