My own answer to Why is it that being embarrassed on one sin should atone for all? It brings dozens of examples for the linguistic phenomenon in question from many places in Hazal. In addition, it notes that the question depends on the accurate text of multiple Talmudic passages and brings almost a dozen relevant medieval manuscripts, and the views and versions of multiple Rishonim. It also provides context for the different possible versions, from yet more Hazalic passages. Finally, it cites a commentator who asks the exact question and answers it.
