docs: Process a buffer for human-readable display.
  
    This function performs the following operation on each of the buffers in `s`.
      1. Truncate input buffer if the length of the buffer is greater than
         `limit`, to prevent large strings from overloading the frontend.
      2. Apply `binascii.b2a_qp` on the truncated buffer to make the buffer
         printable and convertible to JSON.
      3. If truncation happened (in step 1), append a string at the end
         describing the original length and the truncation.
  
    Args:
      s: The buffer to be processed, either a single buffer or a nested array of
        them.
      limit: Length limit for each buffer, beyond which truncation will occur.
  
    Return:
      A single processed buffer or a nested array of processed buffers.
