In side-by-side output the gutter marker was written wherever process_half_line stopped padding the left half (one column past sdiff_half_width), not at separator_pos (the middle of the gutter). Those agree only when the gutter is 3 or 4 columns wide, so the default --width=130 --tabsize=8 (gutter 3) looked right while other widths/tab sizes drifted (e.g. --width=40 placed '<' at column 17 instead of 19). Pad from half_width + 1 up to separator_pos before writing the marker so it lands at the gutter middle, matching GNU sdiff. format_tabs_and_spaces is a no-op when already at/past separator_pos, so narrow gutters are unaffected. Add a regression test at --width=40. Fixes uutils#269
