"Avraham is still standing in front of Hashem" (Vayeria 18:22)
Take a look at the Rashi on that passuq.
Due to Tiqqun Soferim it got switched around, even though the opposite is the case. This was not, however, literally done by some "editor" who changed the text. EG see Iqqar siftei Hachamim 1.(Any such idea of an editorial change could be deemed a perfect mis-understanding.)
IIRC R Dr. MS Feldblum explained that tiqqun sof'rim is an idiomatic expression simply meaning "euphemism". This is only a slightly different interpretation than the Iqqar Siftei Hachamim's. The sentiment is similar. It's not an editorial change to the text, but rather a LINGUISTIC change to say one thing but mean another.
