Sorry to comment on a closed issue. I see the following behavior with
difflib.ndiff which is used under the hood by unittest. The strings that differ
by '-' and 'w' generate different output compared to 'a' and 'w'. I find the
output for diff using '-' and 'w' little confusing and is this caused due to
'-' which is also used as a marker in difflib?
