Question: in the Steinsalts edition (Hebrew) and also the Davka CD-rom edition, where it says SHE MAKDIAKH TAVSHILO BARABIM, they add: KGON YESHU HANOTZRI, a text which does not appear in regular editions. On what would Steinsaltz and Davka base themselves to introduce this wording. Shalom
The DIKDUKEI SOFRIM (a comprehensive work comparing the Girsa'os in many manuscripts and printed editions of the Gemara) there in Berachos records out that all of the early editions of the Shas had the Girsa to which you refer, "Kegon Yeshu ha'Notzri." That is also the Girsa in the manuscripts. Apparently, it was removed by the censor.
In general, you may find our "Girsa section" of the Background to the Daf notes handy. This section appears at the beginning of each Daf's Background notes, and can be accessed from our Website or by Email upon request.
Be well,
