According to the Scintilla Documentation:
> Any markers not associated with a visible margin will be displayed as changes in background colour in the text. A width in pixels can be set for each margin. Margins with a zero width are ignored completely.
All lines with markers, either builtin or used by plugins (`git-changebar`), appear on the white background, which is ugly, especially in dark themes.
This MR disables rendering of markers by making them fully transparent on the overview.
Additionally, it fixes `SETMARGINWIDTHN` for the last (missing) margin:
> 5 margins are allocated initially numbered from 0 to SC_MAX_MARGIN (4). You can view, comment on, or merge this pull request online at:
