See the screenshot for a diff on an edit I made. Actually multiple edits, which might be a contributing factor, but combined into one historically (I guess due to being within a five minute window or such).
The meat of the edit is the adding of the last paragraph. But the diff algorithm seems to have latched on to some words in that paragraph that are in the first point in the bulleted list and then kept drawing the wrong conclusions.
كما ترى، لقد أضفت للتو سطراً جديداً بعد الصورة (ومن هنا جاء ins على ما أعتقد). ولكن تم تمييز ثلاثة أسطر وهو أمر غير ضروري على ما يبدو. وينطبق الشيء نفسه إذا قمت بحذف سطر فارغ؛ سأحصل على del.
