### Explanation

Um... well, this is interesting.

It just so happens that Pip's Pattern type (used for regex) is delimited with backticks. And that backticks can be escaped within a Pattern using backslashes.

... And furthermore, that the code for generating the Pip [repr](https://docs.python.org/3/library/functions.html#repr) of a Pattern is incorrect, because it should escape the backslashes too, but in fact it only escapes the backticks. Which is exactly the behavior this question asks for.

         q  Read a line of stdin
      ``.   Cast it to a Pattern by concatenating an empty Pattern to it
    RP      Get the repr
