…-hang, r=jackh726,wesleywiser Avoid possible infinite loop when next_point reaching the end of file Fixes rust-lang#103451 If we return a span with `lo` = `hi`, `span_to_snippet` will always get `Ok("")`, which may introduce infinite loop if we don't care. This PR make `find_width_of_character_at_span` return `width` with 1, so that `span_to_snippet` will get an `Err`.
